I would say that this issue of divorce, is covered in the scriptures in a way that we all should understand that it is Gods first will that we do all to keep the covenant of marriage. Now beyond what is clearly written, one should take caution to answer to the Spirit of God that abides in us all who are born again. We all know very well that the lust and passions of the flesh will draw us into such relationships that are not in harmony with the standard as to keep our bodies as the temple of the Holy Spirit. I think one should have this as the first great concern, and be very careful not to allow our flesh to draw us into lust. Having said that which is true, and right each believer will and must answer to God, with their own conscience. FOR I SHALL BE THEIR GOD, AND THEY SHALL BE MY PEOPLE, THEY SHALL NOT NEED EVERY MAN TO TEACH THEM SAYING KNOW THE LORD, FOR ALL SHALL KNOW ME FROM THE LEAST TO THE GREATEST SAITH THE LORD.
Now I would suggest that one in this condition, stop all contact with others of the sexual nature, and seek to know the will of God through earnest prayer. If one does not have the ability of themselves to hear the Spirit or to control their own desires? They should ask and pray that God would bring another one of His servants to help them in their battle.
Now there is no condemnation for those who are in Christ.
But we should be willing to be corrected and bring the light of truth upon any darkenss that we have been walking in.
Eph 5:13
Whatever mistakes we have made, if we bring them to Christ, He will make all our darkness into light.
Our very mistakes are turned into those things that help others, when we trust in Him.
