unstoppable the songWhat does the song Unstoppable mean by Rascal Flatts?

I was wondering what this song means? is it talking about our faith in God?? or faith in love? or wat? specifically what does this mean (You find your faith has been lost and shaken,You take back, what's been taken, Get on your knees and dig down deep,You can do what you think is impossible
Keep on believing, don't give in, It'll come and make you whole again,It always will, it always does
Love is unsunstoppable the songtoppable )
It means that even in your darkest times, there is always something or someone to help you back up on your feet. Be it god, be it a friend. But yes Gary and the boys are talking about talking to God. Cause with him, you can do anything. They are also talking about love, love is a wonderus thing. like they say "A light house shinin on the coast that never goes down."
The bible says God iunstoppable the songs Love. So just replace the word Love with God thoughout that whole song and it is just like wow. God is unstoppable...

I think that it means that yeah you may have gotten off the path with God but all you have to do is to get down on your knees and pray and ask for God again and that his love for you and your love for him is unstoppable
