There is not a relationship that is so messed up that God cannot turn it into a miracle.
Matthew 1:18-20, NKJV “Now the birth of Jesus Christ was as follows: After His mother Mary was betrothed to Joseph, before they came together, she was found with child of the Holy Spirit. Then Joseph her husband, being a just man, and not wanting to make her a public example, was minded to put her away secretly. But while he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not be afraid to take to you Mary your wife, for that which is conceived in her is of the Holy Spirit.”
2 Corinthians 6:14, NKJV “Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness?”
Romans 8:28, NKJV “And we know that all things work together for good to those who love God, to those who are the called according to His purpose.”
Greatest Miracle ever happened is the Birth of Christ. God can take what looks bad and messed up and turn it into a miracle. The key to having a right relationship is do not be in a relationship with a non-Christian or a non-practicing Christian. Remember things are not always what they look like. How we respond to what looks like a mess greatly determines the outcome. Agree to do the right thing before you know the outcome. Reactions determine the reach.
