4 Little children, you are of God [you belong to Him] and have [already] defeated and overcome them [the agents of the antichrist], because He Who lives in you is greater (mightier) than he who is in the world.
Have you seen the greatness of God's power and ability that is inside of you? Daily meditation of the Word of God helps you see His great power inside of you, as well as feeds your faith to act on that power. God has given us so much of His goodness and splendor. He thoroughly equipped us to achieve the greater works of His plan.
We just need to see that potential that is within us waiting to come out, through the Word of God. Meditating God's Word will helps us see who we are clearly. The more we see our potential, the more God will be able to craft all of His Promises into divine acts through our faith and trust in Him.
