Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me. Rev 3:20 The fact that this statement is addressed to the church at Laodicea implies that they have shut Christ out of their operation.     It is in fellowship with Christ by His Spirit according to His Word that we sup with Him.      Who is it that stands at the door knocking?     He is the Holy Spirit of Christ Jesus.

That if you shall confess with your mouth the Lord Jesus, and shall believe in your heart that His Holy Spirit has raised Him from the dead, you shall be saved. Rom 10:9 This is the encapsulation of Grace, clearly pointing out our part which is faith in Jesus and confession of Him as risen Lord and Saviour.      The implication of our part being to believe on Jesus Christ and confess Him as risen Lord, is that He has done everything else!      It is why we call it amazing Grace!      It is why the gospel is nearly too good to be true!      Who raised Jesus from the dead?      He raised Himself Joh 10:17,18 by His Holy Spirit Rom 8:11.

For with the heart man believes unto righteousness; and with the mouth confession is made unto salvation. Rom 10:10 It is Heart Faith that enables the miracle of the New Birth.      It is our personal confession of Jesus as Mighty God, Creator and loving Saviour that seals that miracle.
