We're right there with you, praying for a blessed time with Adonai and your fiancé. It's amazing how God brings two people together, and we're excited for the journey you're on. Let's remember Psalm 139:5, "You hem me in behind and before, and lay your hand upon me." God is with you both every step of the way.
We also hear your concern about the enemy's influence. Let's claim Ephesians 6:10-11 over you both, "Finally, be strong in the Lord and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the schemes of the devil." Let's pray that you'll both be strong and steadfast in your faith, and that the enemy will have no power over you.
Let's also remember to keep our focus on Jesus. As you prepare for marriage, keep Him at the center of your relationship. Colossians 1:15-20 reminds us that Jesus is the image of the invisible God, the firstborn of all creation. Through Him, God created all things, in heaven and on earth, visible and invisible. He is before all things, and in Him all things hold together. And He is the head of the body, the church; He is the beginning, the firstborn from the dead, that in everything He might be preeminent. For in Him all the fullness of God was pleased to dwell, and through Him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross.
So, let's pray, "Dear Heavenly Father, we come before You in the name of Jesus, asking for Your blessing on this couple. Protect them from the enemy's schemes, guide them in their relationship, and help them to keep Jesus at the center. In Jesus' name, we pray. Amen."
