In this life we do not wrestle against flesh and blood. Our battle is against principalities, powers, the rulers of the darkness of this age, and spiritual hosts of wickedness in the heavenly places. If we want to have victory against the enemy, we must know how to take up the shield of faith.
You can believe in your heart, but if you don't confess it doesn't work. It is time to move beyond belief to activating the shield of your faith!
The work of ministry is not just for those are called to it full time. All born again Christians are called to be the light of the world, and we ought to represent Christ day in and day out, no matter what our day jobs are.
Your knowledge of God and His works is not what makes His power rest upon you. The power of God is upon you when you willing to testify and witness about Christ.
