Living in God’s Divine Will is a way of life that restores our original sanctity given to us by God, which we lost after original sin.  Jesus tells Luisa Piccarreta this path to holiness is the “sanctity of sanctities” because it entails a profound union of two wills: our human will and Jesus’ Divine Will, fused together in one act of willing, like two hearts being as one.  In unity with Jesus, we allow Him to live in us as He Himself did in His most Holy Humanity: doing only His Father’s will. Living in the Divine Will allows us to return to the God through His Son Jesus, who was always one with His Father, and is therefore the only way back to Him.
