If you play electric guitar in church, I cannot recommend this page/course/academy highly enough. Charl is the guitarist at Victory Church in Jeffries Bay South Africa, and a master at his craft.

(I’ve signed up for a lifetime subscription.) The YouTube channel is also great.
You need to learn the notes on the fretboard. So do I. Here are some resources I’ve created.
