Christ is never content with sin in his church - with any moral or spiritual impurity. God has a big eraser . For I will forgive their iniquity, and their sin I will remember no more. The believer is forgiven every sin the moment he becomes a Christian. And it the Word that is the agent of forgiveness.
Forgiveness is a foundation to making marriage work.
One of the devil's strategies is to convince us to rummage around in the garbage can of forgiven sin. Therefore we must learn to live in openness with our spouses. We should be slow to take offense and quick to grant forgiveness. Christ totally accepted us for who we are - and He totally forgave us. The discretion of a man makes him slow to anger, And his glory is to overlook a transgression.
