Over the years, I have received many letters like yours, and their story of shattered dreams and broken hearts always saddens me. Many admit they ignored the warnings of others, or they let themselves be carried away by their emotions. The Bible says, "A simple man (or woman) believes anything, but a prudent man gives thought to his steps" (Proverbs 14:15).
You say that you hope you have learned something from this experience, and I trust you have. But let me ask you this: What do you think God is trying to teach you through this experience? He may have several lessons for you–but the most important one is to put Him and His will first in your life.
You see, God loves us and wants what is best for us–and that's why we can come to Him and seek His will about every detail of our lives. Did you pray about your decision to remarry, honestly seeking His will about this important decision and asking Him to guide you? The Bible says, "Trust in the Lord with all your heart and lean not on your own understanding" (Proverbs 3:5).
Learn from your past–but don't be bound by it. Instead, begin a new life today by asking Christ to take away your sins and come into your life. Then ask Him to guide you in the future, both in small things and big things. Christ can heal your past and guide your future as you learn to trust Him in everything.
