Matthew 6:33 Seek first the Kingdom of God and His righteousness..." (Look it up)
We can try every method, every tool and every therapist or shrink but until Jesus in the highest prority of your life and in the center of your decsion making there is no real help or hope for your marriage.
To seek requires that His word, The Bible, be a part of your everyday life and that the principles therein become the basis of all your decisions..
Seeking requires that you listen to Him and respond with a heart of complete obedience. Proverbs 3:5,6
Seeking means that you die to being selfish and that His love flow through you and out to others. This especially means loving your spouse.
Do you want to know the secret? Repent once for salvation trusting Christ alone for forgiveness and a saving relationship. Repent many times for sanctification a process of staying on track with God and growing spiritually.
Seek first...FIRST, the Kingdom of God!
