"He that hath received his testimony hath set to his seal that God is true." John 3:33
We can only set to our seal that God is true in any one point of doctrine, experience, or precept when we feel an inward witness that God indeed has declared it. Thus, upon every manifestation of God's goodness to the soul, every application of Christ's blood to the conscience, and every revelation of God's distinguishing grace, it is only as we receive Christ's testimony, experience the inward approbation of it, and feel its sweetness and blessedness that we can set to our seal that God is true. This, we may be well assured, is the only way to know the power and reality of true religion, to understand the Scriptures, and enjoy a convincing testimony that God is our God, Christ our Saviour, the Holy Ghost our Teacher, heaven our eternal home, and that our soul is saved in the Lord Jesus Christ with an everlasting salvation.
And with what divine certainty can such a soul sometimes speak. Sometimes, indeed, we cannot believe anything; it seems as if there were nothing in God's word that we could set our seal to. All seems a mass of confusion, and our ignorance appears so great that we cannot set our seal to any vital truth. But when the blessed Spirit is pleased to testify of the things of God, and we, receiving the testimony of Jesus Christ, walk in the light of that testimony, then there is a holy certainty of and heavenly acquiescence with God's truth. This divine faith will bring us through all our trials and sorrows, and though we may be dragged through a very hell of temptation, yet shall we know God is true. Here, then, is the grand trial of faith; first to receive Christ's testimony, and then to hang upon that testimony, in spite of all opposition from within and without, from feeling its weight, power, and sweetness.
