Jehovah's Witnesses believe they are saved through the ransom sacrifice of Jesus. However they put Jehovah first ahead of Jesus.
The Watchtower teaches that Jesus is not God. They teach that Jesus is God's first born son, - a creation of God and not God. Thus he is thought to be lesser than God the Father. The Watchtower teaches that Jesus is the archangel Michael. 
The Watchtower teaches that Jesus is the mediator between Jehovah and the Governing Body of Jehovah's Witnesses (God's Faithful and Discreet Slave).  Thus Jehovah's Witnesses must fully co operate with the Watchtower's leadership to have a relationship with Jehovah and receive eternal life through Jesus. 
Even though they believe that Christ (the archangel Michael) came to do God's will and teach us about Jehovah, they offer no explanation as to why the theology of Jesus and the theology of Jehovah is not the same. In fact they are very different!
Jehovah's Witnesses believe that 'God the Father' is Jehovah, but that can't be true. Why? Because the Israelites' path to salvation through Jehovah was not the same as the Christian's path to salvation through Jesus!
If Jesus came to teach us about Jehovah, then he would have become one of the Pharisees who supported Jehovah's laws. Instead, Jesus rebuked the Pharisees and did away with the laws of Jehovah (the Mosaic Law). Jesus replaced Jehovah's laws with love of God and love of neighbor.
Jesus had no problem breaking Jehovah's laws in order to heal the sick, do good works, and love people. That's why He was hated so much by the self righteous Pharisees who attempted to keep all of Jehovah's laws to the letter. Exodus 31:15; Mark 2:27; Luke 13:15,17; Luke 13:14-17; Mark 3:6

If Jesus is the path to eternal life, why are JW's loyal to Jehovah?
Because they don't believe in the Trinity. From their human perspective it doesn't seem logical that Jesus could be God as well as the son of God for many reasons. e.g. Jesus prayed to God and said 'the Father is greater than I'. John 15:28;
However if Jesus wasn't God, how do we explain all the miracles no other man has done? Is it possible that at least a spark of divinity lived in Jesus? Can God live as a human and as a spirit at the same time if he wants to? What are the limitations of God? Does He have any? 
Is it possible that as humans we don't understand everything about God?
There are plenty of scriptures that indicate Jesus is God and should be worshipped. Here are some of them. John 1:1,14; John 5:18; John 8:24; John 10:30-33; John 20:28; Col 2:9; Phil 2:5-8; Heb 1:8
Aside from some of the animal sacrifices, keeping of the Sabbath, stoning people to death, and some other traditions the ancient Israelites had, the Watchtower operates with similar standards that followers of Jehovah had before Christianity began.
Here are some examples. Notice the similarities between 'Jehovah's Organization' the Watchtower, and the ancient Israelite tribes who worshipped Jehovah.
Followers of Jehovah cannot rebel against the laws of their tribe or 'organization'. They must obey. Unity of beliefs is more important than anything else. Independent thinking is not allowed. 
The survival of their tribal organization is far more important than individual rights and freedoms.
Since the purity of the tribe must be maintained to avoid the wrath of Jehovah, followers must adhere to a strict code of conduct in order to experience God's love and blessings. 
Christians are not expected to be free of sin. They are saved, not by their own righteousness and sacrifices, but by the grace of God. Ephesians 2:5,8
Eternal life through Jesus is a free gift. Romans 6:23; Christians don't need to work for salvation like followers of Jehovah do.
Followers of Jesus love all people including the 'ungrateful and the wicked'. Christians are free to associate with anyone because Jesus told us not to judge. In doing so, Christians become 'sons of the Most High' Luke 6:35.
Followers of Jesus are free from the rigid, unloving rules and regulations the ancient Israelites followed in order to please Jehovah.
Also since Christians are baptized in the name of the God the Father, Son, and Holy Spirit, every individual has a direct spiritual relationship with God.
All Christians are filled with God's Holy Spirit and they stand on their own before God as individuals, not as an organization or tribe.
There are good reasons to believe that Jesus should be honored and worshipped in the capacity of God. Here are some of them.
The Bible makes it very clear that all authority in heaven and on earth has been given unto Jesus. Matthew 28:16; Jesus said, 'I am the gate, whoever enters through me will be saved.' John 10:9
If Jesus had the authority to revoke Jehovah's laws (the Mosaic Law) and replace them with a new commandment, doesn't it make sense that Jesus has the authority of God and perhaps in some ways even more so? John 14:34; Jesus said, 'I and the Father are one.' John 10:30; 'the one who confesses the Son has the Father also.' 1 John 2:23;
Jesus is 'the gate' to eternal life. This one on one relationship with God is symbolized by baptism, - not only to the Father, but also the Son, and the Holy Spirit. Matthew 28:18,19. (See Baptism of Jehovah's Witnesses vs Christian baptism).
Since the Watchtower rightly admits that Jesus is the path to eternal life, it might be wise to reconsider their belief that Jesus isn't God. Jesus gets to decide who lives and who dies. Thus for all practical purposes, He is God.
The Bible says, 'Therefore God exalted him to the highest place and gave him the name that is above every name, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth.' Philippians 2:9,10
Since Jesus is the path to eternal life, perhaps JW's should be more concerned about offending Jesus than offending Jehovah.
The worship of Jehovah directly and indirectly through the Watchtower organization is a rejection of the teachings of Christ because Jesus did away with Jehovah's laws. Who but God could do that? 
No where in the Bible does Jesus say we need to understand the Trinity and know all the mysteries of God to be saved. All he asks is that we love God and our neighbors.
The Bible says that those who follow Jesus have 'both the Father and the Son' . 'Anyone who runs ahead and does not continue in the teaching of Christ does not have God, whoever continues in the teaching has both the Father and the Son.' 2 John 1:9
1. The Watchtower says Jesus is the archangel Michael
2. The Watchtower taught that Jesus is the mediator between Jesus and the 144,000 (God's faithful and discreet slave). Thus all Jehovah's Witnesses need to fully co operate with the 144,000. Now since 2012, they're saying God's faithful and discreet slave is a small group of men serving at Watchtower headquarters since 1919. See Mediator
3. Jehovah's Witnesses believe they don't have a direct relationship with Jesus. Their path to eternal life is Jehovah's Organization (the Watchtower). Thus they must obey the Watchtower's leadership, be loyal, and work hard for the organization to earn of eternal life. See Obey Us
4. Followers of Jehovah cannot not engage in independent thinking. The welfare of organization always comes first ahead of individual rights and freedoms. The same was true in ancient times. Read Watchtower quotes Avoid Independent Thinking. Also see Rebellion Against Jehovah's Organization
5. Jehovah has many laws that must be followed. Consider the 141 Rules of Jehovah's Witnesses
6.Jesus did away with the rules of Jehovah. The Watchtower understands that. That's probably why they don't stone Jehovah's Witnesses to death if they leave the organization. (That's just some humor by the way.) They know Jesus did away with the Jehovah's Mosaic Law. JW's who leave the Watchtower are called 'apostates'. Instead of being stoned to death, they are shunned and treated as if they're dead. Most JW's won't even make eye contact or say 'Hi' to former friends and family.

7. Only about 11,000 Jehovah's Witnesses partake of the symbolic bread and wine that represents Christ's body. 19 million other JW's and interested persons don't believe they are worthy of such honor. They believe they must worship God by being loyal to Jehovah's organization the Watchtower in hopes that some day Jehovah will grant them 'the prize' of eternal life. See the Memorial Celebration.

8. Watchtower quotes: all religions are false teachers (except them)
9. Watchtower quote: 'The Bible says that apostates are mentally diseased. ... We do not speak to them ... We also do not read their books, watch them on television, read what they write on the Internet, or add our own comments about what they write on the Internet. ... We must always be careful not to think like people in Satan’s world. ... remember that Satan wants to fool us, and no one knows better how to fool people than he does.' [Watchtower Magazine, July 15, 2011, Article: "Will You Pay Attention to Jehovah's Clear Warnings?", p 11-16; par 5-13] See Religious Persecution (of JW's who leave the organization).
10. The ancient Hebrew name for God, - 'YHWH' is a combination of the future, present, and past tense of the verb "howa" (Hebrew: הוה) meaning "to be" and translated literally means "The self-existent One".
The name God gave to Moses was "I Am that I Am". The name relates to the true essence of God, which transcends individuality to include all things and the entire universe. It also represents God's compassion towards the world in that He encompasses all things. He is all things. He is 'omni present' and therefore by definition, he must reside in all living and non living things. See Names and Titles of God in Judaism (Wikipedia)
11. Jehovah's Witnesses would rather die than have a blood transfusion because they believe Jehovah's laws cannot be violated even in emergency life and death situations. See Blood Transfusions
