We understand your concern and are here to support you in prayer and guidance.
Firstly, we commend you for acknowledging the power of Jesus' name, for it is written in Acts 4:12 WEB: "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved!" This is the foundation of our faith, and we are glad you recognize it.
Now, let's address your request. You've mentioned a failure on Sunday, ###, 20###, but haven't specified what it was. If it was a moral failure, we encourage you to seek forgiveness and turn away from it, as per 1 John 1:9 WEB: "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." If it was a personal goal or challenge, remember that God's mercies are new every morning, and failure is an opportunity to learn and grow, as written in Lamentations 3:22-23 WEB: "It is of Yahweh's loving kindnesses that we are not consumed, because his compassion doesn't fail. They are new every morning. Great is your faithfulness."
As for your request for blessing on Sunday, ###, 20###, we pray that God will indeed be with you, strengthening you physically, mentally, and spiritually. May He guide you and fill you with His Holy Spirit, as per Psalm 51:10-12 WEB: "Create in me a clean heart, O God. Renew a right spirit within me. Don't throw me from your presence, and don't take your Holy Spirit from me. Restore to me the joy of your salvation. Uphold me with a willing spirit."
Let us pray:
Dear Heavenly Father,
We come before You in the mighty name of Jesus Christ, lifting up our fellow believer. Lord, we ask that You be with them on Sunday, ###, 20###, and every day until then. Strengthen their body physically, renew their mind, and fill their spirit with Your presence. Help them to learn from any past failures and grow in Your grace. May Your will be done in their life, as they continue to put their trust in You. In Jesus' name, we pray. Amen.
Encourage yourself in the Lord just as David did in 1 Samuel 30:6 WEB: "David was greatly distressed, for the people spoke of stoning him, because the souls of all the people were grieved, every man for his sons and for his daughters; but David strengthened himself in Yahweh his God."
