Have Faith & Don't Doubt

21 And Jesus answered and said to them, “Truly I say to you, if you have faith and do not doubt, you will not only do what was done to the fig tree, but even if you say to this mountain, ‘Be taken up and cast into the sea,’ it will happen. 22 And all things you ask in prayer, believing, you will receive.”  ~ Matthew 21:21-22 (NASB)
