If we had no Bible we should have no certainty that our sins are forgiven. A little girl named Molly said to her aunt who was teaching her about Jesus, "How can I be sure that my sins are forgiven?" "Because God says so," [Footnote: i John i. 9.] was the reply, and then she repeated the text, "If we confess our sins, God is faithful and just to forgive us our sins and to cleanse us from all unrighteousness." Many say, "I believe in the forgiveness of sins," and yet they still carry about the burden of their sins. They see clearly how God can forgive sin, but they cannot realise that it is their own sins which are forgiven. This was the case with Luther. He tells us how, when he was distressed because of his sins, a friend pointed out to him that he would not have real peace unless he claimed God's forgiveness for his _own _sins. It was like a new light flashing into his soul; he saw his mistake and looking up with a beaming face, he said, "I see it now--it is not other people's sins, it is _my_ sins which are all forgiven!" We must not estimate sin and forgiveness by our own standard. When we have given way to sin again and again we feel ashamed to ask God's forgiveness so often but the wonder of it all is that God meets this very feeling of shame with the words, "My thoughts are not your thoughts"; and then He adds, "For I will abundantly pardon," [Footnote: 2 Isa. lv. 7, 8.] which means, I will repeatedly pardon. God's thoughts of sin and His thoughts about forgiveness are far higher than ours. Sometimes I feel quite overwhelmed when I think of how great His forgiving love has been to me. Look again at our Psalm, verse 7, "The testimony of the Lord is _sure_, making wise the simple." The word Testimony means an assurance or a promise from God to the individual soul, and David had such confidence in God he is quite sure He will not disappoint him or fail to keep His word. So he says, "The testimony, or promise, of God is _sure_." It is this certainty which makes David so happy. He seems to be overflowing with joy, for he says, "Thy testimonies also are my delight and my counsellors," [Footnote: Ps. cxix. 24.] and again, "I love Thy testimonies." "Thy testimonies are wonderful, therefore doth my soul keep them. Thy testimonies that Thou hast commanded are righteous and very faithful." [Footnote: Ps. cxix. 119, 129, 138.] The word "Testimony" means also what God has commanded us to believe and also to practise. A native convert in China said the other day, "I began by reading the Bible, but now I am _behaving_ it." This is what David means when he says, "My soul hath kept Thy testimonies, and I love them exceedingly." [Footnote: Ps. cxix. 167.] The question was once asked at a meeting, "Can you point to any text in the Word of God which makes you sure you are saved and safe?" "I can," said one of the company, in a quiet firm voice. "It is John iii. 36, He that believeth on the Son hath everlasting life."
