In this revelation of our Father is the assurance of our forgiveness. Such a God is not one who may or may not be gracious, as He wills; it is "His property always to have mercy." He would not be just in His own eyes, were He unmerciful; He is just to forgive us our sins and to cleanse us from all unrighteousness. Like His Son, He owes us Himself; and His forgiveness is freely ours in the measure that we are able to receive it, that is, in the measure in which we have forgiven others. Jesus at Calvary proves Himself both our Substitute and our Exemplar. He who finds and opens a trail to a mountain-top encounters and removes obstacles, which none of those who come after him need to meet; he makes the path _for them_. When the sinless Jesus found Himself socially involved with His brethren in the low valley of the world's sinfulness, and looked off to the summit of His Father's perfectness, He felt a separation between the whole world and God; and He gave Himself to end it. We shall never know the uncertainties that shrouded Him and the temptations He faced, from the experience in the wilderness at the outset to the anguish of His spirit in Gethsemane and the consciousness of dereliction on the cross. The "if it be possible" of His prayer suggests the alternative routes He sought to find, before He resigned Himself to opening the path by His blood. Since His death there is "a new and living way" for those who know Him, which stretches from the lowest point of their abasement to the very peak of God's holiness. Up that way they can pass by repentance and trust, and down it the mercy of God hastens to meet and lead them. They are forever delivered from the sense of exclusion from God; the way lies open. But he who knows a path must himself walk it, if he would reach its goal; and no one is profited by Christ's sacrifice who does not give himself in a like sacrificial service; only so does he ever reach fellowship with the Father.
