‘For the Scriptures say, “You must be holy because I am holy.”’ 1 Peter 1:16(NLT)
Be someone your spouse can count on and trust.
•••
One way you can reflect God in your marriage is to keep your promises. God doesn’t break His promises based on your behavior and you shouldn’t break yours based on your spouse’s behavior. Look to God and ask Him to help you be a vow honoring spouse and protect you against any lie that Satan tries to tell you. He will always attempt to pull you away from the words that you said on your wedding day when the “worse” rolls around, but you said, “for better or worse.” Be determined to show your spouse that you meant it.
