IMDb says CHANGE IN MY LIFE, performed by John Pagano, was in the soundtrack of the film "Leap of Faith." Allmusic.com says it was written by Billy Straus, and has also been recorded by Sam Harris, M-Pact, The Persuasions, Rockapella, and perhaps some others.

Here's an excerpt, transcribed from a sound sample:

I been lonely, I been cheated, I been misunderstood.
I been washed up, I been put down, and told I'm no good;
But with you I belong
'Cause you help me be strong.
There's a change in my life since you came along.
