John 15:16 You did not choose me, but I chose you and appointed you that you should go and bear fruit and that your fruit should abide...
Jesus chose the apostles and by extension we point out that God chooses us, we do not choose him. Before coming to Christ we are dead men walking. The dead cannot make a choice.
Ephesians 2:1 As for you, you were dead in your transgressions and sins...

Many well meaning Christians spend enormous energy trying to make people see the truth of Christ. Before you become frustrated and burned out you should realize it must be God working, not you. Try to see where and with whom God is working and join Him. Otherwise they may tear you to pieces. Remember they are spiritually dead, not physically dead.
Matthew 7:6 "Do not give dogs what is sacred; do not throw your pearls to pigs. If you do, they may trample them under their feet, and then turn and tear you to pieces.
