Basically, love does not give up. So many things like divorce and the such are a product of giving up. Love is not a feeling that goes away after a while.
Love is an action.
If you love someone, you'll try to work things out. What is needed is God, though. A relationship needs to be centered around Jesus Christ and only then will a good, pure marriage come to be. Therefore, since we have been justified through faith, we have peace with God through our Lord, jesus Christ, through whom we have gained access by faith into this grace in which we now stand. And we rejoice in the hope of the glory of God.
