All of our salvation is of the Lord. All of our salvation is of his grace. He is faithful to perform it and to present his people without spot or wrinkle in the assembly of the elect in life eternal. Such is the thought of the apostle in this verse.

God is faithful.

God is faithful in himself. He does not change. He is the same in all the fullness and glory of his divine being from eternity to eternity. He is the same in all his perfections from eternity to eternity. He is from eternity to eternity devoted to the glory of his holy name.

God is faithful.

God is faithful to his promise. Before the world began he made the promise to save his people from their sins and to give them eternal life with him in his covenant in glory for the glory of his holy name. That promise he revealed in the garden of Eden. That promise he fulfilled in the coming of his Son, Jesus Christ. Jesus Christ is the great revelation that God is faithful. God did not spare his own Son but delivered him up for his people to establish their salvation on the foundation of Christ’s perfect righteousness. And God raised up Jesus from the dead and set him at God’s right hand, and from there Jesus will come to judge the quick and the dead.

God is faithful.

God is faithful who calls you. You were conceived dead in trespasses and sins, by nature far from God and from his covenant. Spiritually, you were one with the world. Yet you were engraved upon the palms of God’s hands from all eternity, and you were the apple of his eye. And he called you according to his eternal purpose. He addressed you with his powerful and creative Word in the very depths of your being. He summoned you as light out of darkness, calling you out of darkness into his marvelous light. He made you alive and placed you in abiding communion with Jesus Christ. Yes, the God of peace sanctify you wholly! So that with that calling you are separated from the world and joined unto Christ in your whole life.

God is faithful.

God is faithful to the end. He did not call you for a day, for a week, for a month, or for a year. He called you forever. Faithful is he who calls. He called you at some time. When, I do not know. Likely, you do not know either. That is known unto God. Yet he ever speaks to you according to his eternal purpose. He speaks by his powerful and creative and sustaining word. He constantly calls to you so that his Word is the power of your salvation constantly every day to preserve you blameless unto the coming of the Lord Jesus Christ.

Oh, he is faithful over against your frequent unfaithfulness. He is faithful over against all the assaults of the devil and the temptations of the world. He is faithful to preserve you unto everlasting life in heaven.

He will call once yet, and you will be brought home in your soul.

And at the time appointed, he will send Jesus Christ in his faithfulness. And then, yet again, he will call, and you will come out of your grave and be made perfect, body and soul, to enter into your eternal inheritance. He is faithful who calls you, and he will perform it.
