In Luke 4:5-7, “And the devil took him up and showed him all the kingdoms of the world in a moment of time, and said to him, “To you I will give all this authority and their glory, for it has been delivered to me, and I give it to whom I will. If you, then, will worship me, it will all be yours.” (ESV). That authority had been given to Adam, but he surrendered it to Satan and the fall. Though it was delivered to him, it didn’t belong to him. It belonged to the One to whom he offered it. Jesus came to take it back and to give it back, which He fulfilled in His death, burial and resurrection.
After Peter affirmed that Jesus was “the Christ, the Son of the Living God, Jesus said it was on that rock of revelation that He would build His church and “the gates of Hades will not overpower it. I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven.” (Matthew 16:18-19 NASB).
This promise was fulfilled in Matthew 28:18-20, “And Jesus came and said to them, ‘All authority in heaven and on earth has been given to Me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age'”.
Satan couldn’t give Jesus what was already His, and Satan can’t take back from us what Jesus has given us. So stand firm in your faith, knowing Jesus’ victory means your victory!
