Our Lord publicly proclaimed, that every one who believed on him, as his true disciple, did not believe on him only, but on the Father who sent him. Beholding in Jesus the glory of the Father, we learn to obey, love, and trust in him. By daily looking to Him, who came a Light into the world, we are more and more freed from the darkness of ignorance, error, sin, and misery; we learn that the command of God our Saviour is everlasting life. But the same word will seal the condemnation of all who despise it, or neglect it.
Here is a plain declaration of Christ's coming from the Father, and his return to him. The Redeemer, in his entrance, was God manifest in the flesh, and in his departure was received up into glory. By this saying the disciples improved in knowledge. Also in faith; "Now are we sure." Alas! they knew not their own weakness. The Divine nature did not desert the human nature, but supported it, and put comfort and value into Christ's sufferings. And while we have God's favourable presence, we are happy, and ought to be easy, though all the world forsake us. Peace in Christ is the only true peace, in him alone believers have it. Through him we have peace with God, and so in him we have peace in our own minds. We ought to be encouraged, because Christ has overcome the world before us. But while we think we stand, let us take heed lest we fall. We know not how we should act if brought into temptation; let us watch and pray without ceasing, that we may not be left to ourselves.
The Spirit of God is the Spirit of love. He that does not love the image of God in his people, has no saving knowledge of God. For it is God's nature to be kind, and to give happiness. The law of God is love; and all would have been perfectly happy, had all obeyed it. The provision of the gospel, for the forgiveness of sin, and the salvation of sinners, consistently with God's glory and justice, shows that God is love. Mystery and darkness rest upon many things yet. God has so shown himself to be love, that we cannot come short of eternal happiness, unless through unbelief and impenitence, although strict justice would condemn us to hopeless misery, because we break our Creator's laws. None of our words or thoughts can do justice to the free, astonishing love of a holy God towards sinners, who could not profit or harm him, whom he might justly crush in a moment, and whose deserving of his vengeance was shown in the method by which they were saved, though he could by his almighty Word have created other worlds, with more perfect beings, if he had seen fit. Search we the whole universe for love in its most glorious displays? It is to be found in the person and the cross of Christ. Does love exist between God and sinners? Here was the origin, not that we loved God, but that he freely loved us. His love could not be designed to be fruitless upon us, and when its proper end and issue are gained and produced, it may be said to be perfected. So faith is perfected by its works. Thus it will appear that God dwells in us by his new-creating Spirit. A loving Christian is a perfect Christian; set him to any good duty, and he is perfect to it, he is expert at it. Love oils the wheels of his affections, and sets him on that which is helpful to his brethren. A man that goes about a business with ill will, always does it badly. That God dwells in us and we in him, were words too high for mortals to use, had not God put them before us. But how may it be known whether the testimony to this does proceed from the Holy Ghost? Those who are truly persuaded that they are the sons of God, cannot but call him Abba, Father. From love to him, they hate sin, and whatever disagrees with his will, and they have a sound and hearty desire to do his will. Such testimony is the testimony of the Holy Ghost.
The apostle knew that he would justly have perished, if the Lord had been extreme to mark what was amiss; and also if his grace and mercy had not been abundant to him when dead in sin, working faith and love to Christ in his heart. This is a faithful saying; these are true and faithful words, which may be depended on, That the Son of God came into the world, willingly and purposely to save sinners. No man, with Paul's example before him, can question the love and power of Christ to save him, if he really desires to trust in him as the Son of God, who once died on the cross, and now reigns upon the throne of glory, to save all that come to God through him. Let us then admire and praise the grace of God our Saviour; and ascribe to the Father, Son, and Holy Ghost, three Persons in the unity of the Godhead, the glory of all done in, by, and for us.
