Many people often say find a man who loves you more than he would ever love anyone else. Well, if you want a long-lasting relationship, I would advise you to look for someone who loves God more than he or she loves anyone else. Since a person who loves God fears and Obeys Him.
One of the ways you can put God first in your relationship is through strengthening your personal relationship with God. He can only work in your relationship if you let him work in you first. Love God first before your partner. If you love God, you will fear him and avoid doing what does not please Him. Pray for your partner. Pray together since a family that prays together stays together. Read the bible together and make it a habit.
Acknowledging God in your relationship does not make it smooth or easy. There will be a hard time and challenging moments. However, putting God first and having a good relationship with Him will make you stronger in trials. It will also make you wiser.
