Your prayer reflects the heart Jesus calls us to have, to bless those who curse you and to pray for those who have mistreated you. It is painful to be mocked, used, and turned against, and God sees that hurt. Scripture is clear that He will bless those who bless His people and that He will deal justly with those who curse them, but He also calls you to release those who have hurt you into His hands and to ask for good for them rather than holding on to resentment.
That desire to pray for them is right. The love and blessing you have received from God through Jesus Christ was not given to you to keep to yourself, but to share with others, even with those who have opposed you. As you pray for them, you are walking in the way of Jesus, who prayed for those who rejected Him, and you leave the matter of justice to the Lord who goes before you and will not forsake you.
Your second request, that God would bless you so that others may hear of the great things He is doing in your life, is also understandable. It is good to want your life to be a testimony of His goodness and grace. Remember as you share that testimony that His blessing does not come because you have been especially benevolent or because you handled a difficult situation well. We do not receive from God on the basis of our own good deeds or performance, as if we could say, Lord, did you see how well I handled that. We receive on the basis of His promise.
That promise goes back to Abraham. God promised Abraham, in blessing I will bless you. Through faith in Jesus Christ you become a child of Abraham, not by natural descent and not by keeping the law, but by believing God as Abraham believed. Jesus opened the door for you to enter that covenant. He redeemed us from the curse of the law by becoming a curse for us when He hung on the tree, so that the blessing promised to Abraham might come to us through faith. Because His work for you in Jesus never ceases, your failure to perfectly keep the law cannot take away the blessing God has promised you.
So you can rehearse what God has done, how He brings His people out of bondage and into a place of blessing, not to boast in yourself but to point to Him. Tell of His mercy that brought you out, His faithfulness that sustains you, and His power that keeps you. That kind of testimony gives glory to His name and invites others, even those who have mocked you, to see that God is gracious and that He keeps His word.
May the Lord bless you and keep you in His love and fill you with His Spirit. May you walk in the conscious presence and fellowship of God, growing in grace and in the knowledge of our Lord and Savior, and may your life show forth His goodness so that others may hear and be drawn to Him. In Jesus name we pray that He would work in the hearts of those who have hurt you, bring them to know His mercy, and bring peace where there has been strife.
