When one starts to walk in this Rhema rather than just Logos, we will change.
When the supernatural opens up in front of us we have no choice but to speak from the Truth
See here how Simon Peter walks in Rhema that Jesus acknowledges. Peter means stable stone. Bar Jona means unstable as a reed.
Peter’s Confession of Christ
Now when Jesus came into the district of Caesarea Philippi, He was asking His disciples, “Who do people say that the Son of Man is?” And they said, “Some say John the Baptist; and others, Elijah; but still others, Jeremiah, or one of the prophets.” He *said to them, “But who do you say that I am?” Simon Peter answered, “You are the Christ, the Son of the living God.” And Jesus said to him, “Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven.
This shows that the old nature cannot change except through the spirit of revelation. Simon Peter became stable as a rock as a result of the revelation.
The same happened with Melchizadek and Abram. Abraham changed forever when he was given the bread.
When the two disciples were revealed to by Jesus at the meal off the road to Emmaus, they changed even though their hearts burned with his words earlier as a stranger. When the supernatural kicked in, revelation occurred.
We need revelation to change. Pray revelation of Jesus into your unbelieving friends. God will honour these declarations you make.
