Please pray for my brother who Sam who plans to get married. Please pray that God's perfect will would be done. If it is His will to marry this girl, that the good hand of the Lord would be on them. If it is not of God, please pray that God would give Sam (believer) the wisdom to get out of the relationship. Pray that He can trust God in this.
Thank you so much for your prayers.

Dear Lord, I pray that You will guide Sam to make the right decision in this situation. If it is your will for him to marry this girl, give him peace so that he knows that he is making the right decision. If it is not your will, please guide these two people to realise this before they get married. In Jesus' NAme. amen
