If you are single learn to love yourself and God before you bring anyone else in the picture
If you are engaged to get married be honest with who you are and where you are, address past hurts and disappointments before you say I do, so you can get past your pass so you can embrace your future. So you can love the one your with and not still struggle from the hurts of those they mistreated you.
If your married, remember to love your spouse as you love yourself. And be true to the 3 that make 1 because of you mistreat 1 of the three you will have to answer to the 1 that created you in his image.
Marriage is not easy but if we do it God's way it is not as difficult as some make it seem.
