Is God Really Able?

Real Dudes,
To be honest, sometimes in my head I wonder if God is really able to do something. Is He really able to save anyone, even the chiefest of sinners? Is He really able to heal the sick, even someone with stage four cancer? Maybe it's my upbringing that influences my doubt at times, but yesterday, a phrase from the song More Than Able by Elevation Worship kept replaying in my mind. It's the phrase, "who am I, to deny, what the Lord can do?" Men...think about it. What limitations have you been putting on the Lord? You might say that God is able to do the "impossible," but maybe your genuine thoughts and actions reflect differently.
Here's the link to this song...let me encourage you to take some time to listen to it and apply it the way the Lord would have you to. https://www.youtube.com/watch?v=dQ1xxoP7NJk
Enjoy,
