I need help finding the name of a song!?

OK I heard this song in marshalls and it sounded like it was talking about God so it's probably a Christian song! So it goes "i'm comin' on" and that's all I know im sorry! It may be hard! But it kind of sounded like a song today, like dynamite or dj got us falling in love" or something like that...but i think it might have been a christian rapper! Thanks!!!
