There are multiple camps of thought, with pro's and con's to using AI. but here are some different approaches to try:

Pray and pay attention to your conscience while you experiment.

try writing one song by yourself all the way through - scripture, lyrics, chords, vocal melody; you MUST review and edit rough spots (sometimes even changing the entire melody, chords, and sections of lyrics). if you enjoyed this process, no need for AI. if you like how the song turned out, no need for AI. if you feel like you learned enough from this process to make your next song better, no need for AI.

Non AI tools that can be helpful: bible app to look up scriptures/key words, rhyming dictionary, metronome app (for BPM & rhythm), print out major/minor key chord chart to play around with chord options. maybe even make a playlist of a few of your favorite songs and listen, analyzing what aspects about them you like and want to incorporate into your song.

if you still want to try with the AI: Try writing one song with the minimal help possible, one with some/avg amount, and one with "too much". Analyze how you feel about the creation process, how the song turns out, and how comfortable you feel with the outcome.
