Hindsight is 20/20

"Hindsight is 20/20"...so goes the saying.
We say that when a decision is made and things go wrong. The reality is that God's providence is better than 20/20 vision. Don't moan over the "bad" stuff- lean into God and see what He want to do.
Where do you need to seek a course or action that can only be explained by the Holy Spirit? Perhaps in the area of forgiveness, repentance and reconciliation?

The Christian life is a supernatural life, but when things go well and people do what we want, then we don't need the Holy Spirit.
A key test of the supernatural life is when you are sinned against or take offense at something or someone.
The Bible DOES speak to the question of "How do we respond when someone sins against us?" - Col 3:13
Gospel living asks, "What is the present value of the cross for my life in this moment?" Col 3:13 points us to what God has done for us so that, by faith, we make it a present reality.

We ignore Scripture at our own peril.
Paul Tripp - Lost in the Middle - p67-68 - it is easy in a time of hurt or disappointment to let the hurt set the agenda in our lives.
Christian living is letting the Scripture, not our hurt/anger/disappointment set the agenda

Misc thought...
The only thing between you and a better marriage is your sin.
