There actually is Scripture that talks about taking a believer home when that believer continues in rebellion.
Paul speaks of it in 1 Cor 5:5 hand this man over to Satan, so that the sinful nature may be destroyed and his spirit saved on the day of the Lord. And in 11:30 when Paul talks about many being sick and asleep (dead). God takes those out of the fold so that they will not pollute the church. But, God expects the congregation to outcast those who deliberately continue in sin (Matt 18:15-17) and to treat them as heathen. However, Jesus identifies him as "brother" meaning a member of the Family of God—a believer.
John says there is no prayer for this kind of sin, 1 John 5:16-17 If anyone sees his brother sinning a sin which does not lead to death, he will ask, and He will give him life for those who commit sin not leading to death. There is sin leading to death. I do not say that he should pray about that. 17 All unrighteousness is sin, and there is sin not leading to death.
The question is not “Do you believe that an individual who is continuing in a sinful lifestyle, can, at the same time, have and be appropriating saving faith?”
Let’s take a look at King Saul: 1 Samuel 10:9 And it came about, that when he went away from Samuel, God gave him a changed heart: and all those signs took place that day. God changed Saul from the fearful young man he was re: 1 Samuel 10:22. The Spirit of God came upon him and he ruled as Israel’s king. The trouble began when Saul disobeyed the words of Samuel who wrote in a book how Israel’s king should behave.
God removed the kingdom from Samuel’s authority, but there isn’t any scripture that states God took back the changed heart He had given Saul. The disobedience that Saul exhibited built a wall between him and God to the point not even the prophets (of which he was one) could disintegrate the stubborn streak.
Earlier, I wrote a series on worship. I have studied the differences between early biblical worship, and today’s worship. I’ve studied how the New Testament churches worshiped and how Christians of today seek the warm fuzzies rather than the glory of God.
It is so sad we are set on this path of desensitized, and rebellious behavior on one hand; and on the other we profess Jesus is Lord. Where is the sincerity of real worship? Where is the lifestyle that proclaims Jesus is Lord?
