http://www.worshiptogether.com/ is a great resource-website to find Christian song lyrics and guitar chords.
If the song you am searching for is available (which is more often than not), Worship-Together becomes a single point resource to get all of the following:
- Guitar chords and lyrics
- Song video (sometimes an instructional)
- Link to purchase the MP3
- Link to purchase the ChordPro file
Most of the newer Christian song lyrics and chords are easily available here mainly because Worship-Together has established tie-ups with a number of major record labels and artists.
