Galatians 2:19 “For I through the law am dead to the law, that I might live unto God.”

Clearly the law is not for a righteous man (born again of God’s Spirit) for in Christ the law was fully met. Law is for the unregenerate man who must be restrained from committing evil until he goes to Christ in faith to be set free from the slavery of sin and the condemnation of the law.

You are correct saying, “[Phil 1:6 being confident of this very thing, that He who has begun a good work in you will complete it until the day of Jesus Christ]. Nobody appointed us as each other’s moral policemen, so how can we ever try to assume that function?”

But, for example, we see in churches the marrying of divorcees which is a decision by the pastor to make a moral judgement that divorce and remarriage is ok. But, Mark 10 defines divorcees marrying another as adultery. True, it is not for us to judge them, but does that somehow mean we are to condone the marriages/adultery of these “immature” Christians. And this without regard of the bad example it sets to others seeking justification to end their marriages too (thinking that the grass is greener on the other side).

How do you handle such a delemma as this? Yes, we can trust that God is doing a good work in the lives of Christians but it would appear that we are placed in situations sometimes where we make decisions of condoning bad behaviour in other Christians and that without regard of the bad example it sets to others being tempted to act selfishly.
