‘Our Father which art in heaven!’ To appreciate this word of adoration aright, I must remember that none of the saints had in Scripture ever ventured to address God as their Father. The invocation places us at once in the centre of the wonderful revelation the Son came to make of His Father as our Father too. It comprehends the mystery of redemption— Christ delivering us from the curse that we might become the children of God. The mystery of regeneration—the Spirit in the new birth giving us the new life. And the mystery of faith—ere yet the redemption is accomplished or understood, the word is given on the lips of the disciples to prepare them for the blessed experience still to come
