Why does humanity not see creation as God's own handiwork? In this sermon on Psalm 8:3–4 titled "Blinded by Sin," Dr. Martyn Lloyd-Jones addresses this important theological question and shows its significance for the Christian life. The reason that humanity can look at creation and believe it is anything other than the creation of God is because they are blinded by sin. All are born in sin and naturally opposed to God. So they reject God, not because of reason, but because of sinful prejudice. The psalmists teach this, but it is also seen in the New Testament through the life and ministry of Jesus when He performs great signs and wonders to the people. But in the end, the people still cry out for Him to be crucified, for they still did not believe that He was God's Son. This is because of the sinful principle in all hearts. What is the answer to humanity's blindness and hard-heartedness? The answer is only found in the grace of God in Jesus Christ. Only by God giving His Son and opening the eyes of sinners can anyone be saved. Salvation is wholly a gift of God wherein He gives salvation freely as a gift.
