I call this the Jesus paradox
Jesus says judge not less you be judged and He speaks of pointing out the speck in your brother’s eye. I realized that when I as a Christian throw these in someone else’s face, I have just violated them myself. In judging someone for pointing out the speck in my eye, rather then dealing with the splinter in theirs, then aren’t I in affect judging there to be something in the other’s eye and therefore must have a splinter in my own? ?If I accuse someone of judging me aren’t I also condemning them for having been judgmental towards me? Isn’t that condemnation in and of itself a judgment?? My point is, Jesus seems to have set up much of His teaching so that His admonishments can only be used by me on me. Jesus is looking to do His will in me and He wants to do the same in you. He doesn’t ask me to fix you, Jesus asks me to point you to Him.
Another aspect; In 1 Corinthians 6:9-10 Paul makes a list of some of the unrighteous who will not inherit the Kingdom of God. This list assumes that the individual is choosing to remain in the "unrighteous" life style. Unrighteous is Paul's a way of saying not right or in tune with God.
If a murderer accepts God's gift of salvation by faith in Jesus, than he has been made right with God. But if he continues in his murderous lifestyle, then there is no way his faith conversion was for real to begin with for by his fruits he is known. Only God can judge his heart, but by his actions I can make a judgement call as to wether I should let my teenage daughter date him.
Now change murder to homosexuality, theft, lying, adultery, covetousness, and there is probably something in there for each of us. But slipping up and repenting is not the same as continuing in the life style. God wants Jesus to be the only lifestyle you identify yourself with. He doesn't want to be number one on a list of ten. He wants to be number one on a list of one.
