All David had was his faith in God and a rock to defeat a giant. Therefore, all you need is faith in ‘THE ROCK’ (not Dwayne Johnson) to defeat yours! If you are facing what appears to be an unbeatable obstacle(s) in your life, you must remember that you serve and unbeatable, undeniable, undefeated God!! I John 4:4 reminds us that we belong to God and we have already won victory over our people [our giants] ((HALLELUJAH))because the Spirit who lives in us is greater than the spirit who lives in the world. THANK YOU JESUS!!!
