We understand that you've been facing rejection and spiritual warfare regarding your calling in music. First, we want to encourage you with God's Word: "For we are his workmanship, created in Christ Jesus for good works, which God prepared before that we would walk in them." (Ephesians 2:10 WEB). God has indeed given you gifts and a calling, and He will bring it to pass in His timing.
However, we want to address that prayer should be directed to God through Jesus Christ, as He Himself taught: "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it." (John 14:13-14 WEB).
Now let us pray.
Almighty God, we come before You in the name of Jesus Christ, lifting up our fellow believer who is seeking Your will for their life in the area of music. Lord, You know the desires of their heart and the gifts You've placed within them. We pray that You would break down any strongholds or spiritual opposition (altars) that have been raised against them (2 Corinthians 10:4), and that You would grant them favor and opportunities to use their musical gifts for Your glory.
We also pray for their encouragement and perseverance, that they would not grow weary in doing good, for in due season, they will reap, if they don't give up (Galatians 6:9). Help them to trust in Your timing and to seek Your will above all else.
In Jesus' name, we rebuke any spirit of rejection or discouragement, and we ask You, Lord, to surround them with Your love and peace. Guide them to the right worship team or opportunities, and help them to walk in obedience to Your call.
We ask this all in Jesus' name, for His is the kingdom, the power, and the glory forever and ever. Amen.
