We know that God is true because we have proved him. Sometimes this comes through the hearing of the Word—as we listen our faith is confirmed. But there is doubtless besides this, a special and supernatural work of the Holy Spirit, whereby men are assured that they are born of God. You will observe in one place the apostle says that the Spirit ‘beareth witness with our spirit, that we are the children of God;’ so that there are two witnesses—first, our spirit bears witness, that is, by evidences: I look at my faith, and see myself depending upon Christ, and then I know, because I love the brethren, and for other reasons, that I am born of God. Then there comes over and above the witness of evidence, faith and feeling, the Spirit himself bearing witness with our spirit. Have you not felt it? I cannot describe this to you, but you who have felt it know it. Did you not the other day feel a heavenly calm as you meditated upon your state and condition in Christ? You wondered where it came from. It was not the result of protracted devotion, but it stole over you, you knew not how it was, you were bathed in it as in sunlight, and you rejoiced exceedingly. You rejoiced in Christ—that was the basis of confidence, but that confidence came through the Spirit bearing witness with your spirit. And this has occurred sometimes in the midst of sharp conflicts just when dark despair seemed ready to overwhelm you. You may have enjoyed this comfort under peculiar trials, and losses of friends, and you may expect to have it when you come to die. Then, if ever in your life, you should be able to say, ‘I will fear no evil: for thou art with me.’
For meditation: We must not regard the Holy Spirit as a loose cannon giving us feelings, experiences and revelations which are nothing to do with the Scriptures. But he can confirm personally in our hearts what God has said in his Word and done in our lives (Romans 8:14–16; Galatians 4:6; 1 John 3:24; 4:13).
