Hi Mike,
I'd condense/replace some words to give the lyric greater impact, keep or sweep smile

Jesus is my GP
Mike Parrish

Verse 1
Sin is all around me
IT gets harder to resist
Seems The older that I get
The thicker is the mist
But there's someone to guides me
A lighthouse in the fog
Jesus is my GPS
I'm led by the son of god

Chorus
Jesus is my GPS
He's my map in times of stress
Every wrong road I go down
He gently says to turn around
Till the path is up and straight
And I'm positioned at the gate
Heaven is my next address
Cause jesus is my GPS

Verse 2

But my journey isn't over
I keep heading toward the cross
Knowing Aware that the devil's there
If ever I get lost
(I'd add 4 more lines here before another Chorus)
Repeat chorus [s][/s]
