Let such as love Thy salvation say continually, “Let God be magnified.” – Psalm 70:4
We love God’s salvation because, in addition to the display of wondrous love, it is so safe a salvation, so real, so true: we have not given heed to cunningly devised fables; we have not chanced our souls upon a fiction. We run no risk when we trust the Savior.
Did God lay on Christ my sin? Was it really punished in Him? Then there cannot exist a reason why I should be condemned, but there are ten thousand arguments why I should for ever be “accepted in the Beloved.” “Who shall lay anything to the charge of God’s elect? It is God that justifieth. Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.” Substitution is a basis for intelligent confidence; it satisfies both the demand of the law and the fears of conscience; and gives to believers a deep, settled, substantial peace, which cannot be broken. We love this salvation because we feel that it places a foundation of granite beneath our feet instead of the quicksand of human merit. Justice being satisfied is as much our friend as even mercy herself; in fact, all the attributes unite to guarantee our safety.
We love God’s salvation because it is so complete. Nothing remains unfinished which is necessary to remove sin from the believer and give him righteousness before God. As far as atonement for sin is concerned, the expiation is most gloriously complete…when our Divine Lord went up to Calvary, and on the cross gave up His body, His soul, His spirit, a sacrifice for sin, He finished transgression, made an end of sin, and brought in everlasting righteousness. Herein, my brethren, we have strong consolation, the immutable things wherein it is impossible for God to lie, His word and oath, are our immovable security. By the atonement we are infallibly, effectually, eternally saved, for He has become the “author of eternal salvation, unto all of them that obey Him.” ~ C.H. Spurgeon
