Your prayer asks the Father to create in you a new worshipper, and that is a good request, but you must understand what a new worshipper truly is. Do not be like Herod, who said he would come and worship Christ while in his heart he intended to slay Him. Many who come to the altar with outward reverence are still ruled by a tyrant more wicked than Herod, even Mammon. Covetousness, lust, pride, and love of praise can make you appear a suppliant while your deeds show the contrary. So before you ask for a trained voice or a strengthened faith, ask the Spirit to search your heart and put to death every passion that grieves the kingdom of Christ. A new worshipper is not made by external gifts but by inward purity.
The Lord said that God is Spirit, and those who worship Him must worship in spirit and in truth. He did not mean that you should neglect the body altogether, but that the service of the incorporeal God must be offered by that in you which is incorporeal, namely the soul and a pure mind. The old sacrifices of sheep and calves are gone. Circumcision of the flesh is nothing. What remains is to dedicate yourself to the Lord, to make yourself a holocaust, to offer a living sacrifice, which is your reasonable service. This means circumcising not your flesh but your evil thoughts, crucifying yourself, and slaying your unreasonable desires. If you want your worship to glorify God, let your life be a continual self-offering. Pray not only for a voice that sings well, but for a heart that obeys well.
You ask to draw close to God, and you quote the promise that if you draw near, He will draw near to you. But remember what it means to call God Father. That one title carries with it remission of sins, removal of punishment, righteousness, sanctification, redemption, adoption, inheritance, brotherhood with the Only Begotten, and the supply of the Spirit. You cannot draw near while you are still serving another master. If you bow before God in prayer but in your daily life you obey covetousness or wrath or lust, then you are not a true worshipper but an idolater, serving the passions rather than the Creator. Draw near therefore with a broken and contrite spirit, confessing every secret sin, and putting away every known transgression. Only then can your drawing near be genuine.
You pray that every gift placed within you be awakened, and you ask for faith, healing, or whatever the Spirit has given. But do not envy another person's gift or think yours is too small. There are diversities of gifts, but the same Spirit. The Spirit gives the word of wisdom to one, the word of knowledge to another, faith to another, gifts of healing to another, and all from the same Lord, the same God who works all in all. Whether your gift is great or small, it is not yours to boast in, but His to use through you. Wherefore if you desire your gift to be awakened, humble yourself. A soul puffed up with pride cannot contain the Spirit's power. Be willing to be last, to serve unseen, to take the lowest place.
Meditate on His Word day and night as you have prayed, but let that Word be a sword to you, not just a song. The sword of the Spirit is the word of God. It pierces to the division of soul and spirit, of joints and marrow, and discerns the thoughts and intentions of the heart. Do not read Scripture merely to find phrases for prayer or to improve your speaking. Let the Word judge you. Let it expose your selfishness, your unforgiveness, your love of ease. Let it cut away every branch in you that bears no fruit. Then your voice, trained or simple, will carry weight because it comes from a purified heart.
Finally, prepare for Kingdom service by imitating the wise men who came from afar. They were not put off by the poor estate of the Christ child, for they worshiped not a man but God. They opened their treasures and offered gifts, not to a mere teacher, but to the Word made flesh. They had no outward reason to bow down except the illumination God had placed in their minds. In the same way, let your worship be born from the Spirit's light within, not from the sight of your eyes or the approval of others. Offer to Him knowledge, obedience, and love. These are the gifts that please Him far more than a trained voice lifted without a contrite heart. Let your worship glorify Him not by outward show but by a life that denies itself, takes up the cross, and follows the Lamb wherever He goes.
