Jesus said God is kind to the ungrateful and the wicked. We are not to judge. Luke 6:27-41 Jesus himself associated with sinners and ate with them.
When we separate and isolate ourselves from the world God created, we are isolating ourselves from the source of love. We are not sons of the Most High because we are not following God's example of love.
It was the Pharisees who loved to separate themselves from sinners and those who were not as righteous. Mark 2:16; Luke 15:1-7. Christians who obey the Apostle Paul have strayed from the teachings of Jesus. They have created a new religion. It's a mix between what Jesus taught and the values of the Pharisees who opposed Christ. Jesus warned his followers about the 'leaven' or yeast of the Pharisees. He knew they would add rules and regulations to appear more righteous and worthy than everyone else. Mark 8:15; Matthew 16:6,11,12; Luke 12:1; Paul called himself a Pharisee AFTER he became a Christian. Acts 23:6; The Bible indicates that the Apostle Paul and other Pharisees became Christians after Jesus died. Acts 15
Christians who follow the Apostle Paul and the teachings of the Pharisees may be following the Bible but Jesus has the words of eternal life. 'For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.' John 3:16; All authority has been given unto Jesus, Matthew 28:18;
Jesus warned us about the leaven of the Pharisees. It started almost immediately after Jesus died. It was the Apostle Paul and other self proclaimed Pharisees in the early Christian congregation who deviated slightly from the teachings of Christ. Even though they meant well and were sincere, the Pharisees disagreed with Jesus when he was alive. After Jesus was resurrected, the Pharisees were able to introduce the 'leaven' that Jesus warned his followers about. The leaven of the Pharisees was separateness, self righteousness, and judgment of those not as worthy. Get The Facts About The Apostle Paul
