God doesn't reject anyone

“All that the Father gives Me will come to Me, and whoever comes to Me I will never drive away.” John 6:37
This verse should bring us great comfort. Many times we can feel unworthy to approach God – and rightly so, because He is perfect and we have broken His Law. We are without excuse, and if it were not for the blood of Jesus Christ, we could only expect the punishment of death for our sins (Rom. 3:23). But Jesus came to bridge the gap between mankind and God, and now the way is open for anyone who would come. God will not drive anyone away who wants to come to Him. If someone you know feels as if they are being rejected by God, know that it is not God who is rejecting them, but Satan trying to prevent them from coming. One of the primary works of the Holy Spirit in the lives of unbelievers today is drawing them to Christ. God “wants all men to be saved and to come to a knowledge of the truth” (1 Tim. 2:4). He will not reject anyone.
In this verse we can also see the two sides of the predestination-free will coin. “All that the Father gives Me will come to Me” – those who have been predestined. No-one can be saved unless they have first been drawn to Christ (John 6:44). “and whoever comes to Me” – by their own free will. The Holy Spirit draws us to Christ, but we must also respond to that drawing.
