Peter’s confession is the rock upon which Christ will build his church. Notice the Greek ” will be having been” bound in heaven, which means that which is already done in heaven counts in building His church.
1 Peter 5:6 Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time.
But Zion said, “The Lord has forsaken me,
And my Lord has forgotten me.”
15 “Can a woman forget her nursing child,
And not have compassion on the son of her womb?
Surely they may forget,
Yet I will not forget you.
16 See, I have inscribed you on the palms of My hands;
Your walls are continually before Me.
