God is great, because He created and predestined you for greatness.
God is a great God. Even when there are technological advances, nothing can ever replace Him nor His works. His greatness is beyond what a human mind can comprehend.
God is great! He is the source of abundant love, peace and power.
God is great! In times of pain, He gives power. In times of sickness, He provides healing and after a loss, He is able to restore what was lost.
God does not have to prove Himself to anyone, but He still does anyway. Through Creation, God has proven over and over again, that He is so great.
There is never a giant problem for a God so great.
