The heavens scream out and tell us of God’s surpassing worth (Ps. 19:1; Rom. 1:20). God’s glory is beyond our comprehension. For example, do you know how far away the closest star is (besides the sun)? It is approximately 4 light-years away. A light-year is the length that light travels in one year. Light travels 186,000 miles per second and there are 31,536,000 seconds in a year. A light year is really far. One light year is almost 6 trillion (6,000,000,000,000) miles! So, it takes four years for the light from the closest star to get to us.
The universe is also vast beyond comprehension. Hugh Ross said, “Somewhere around 50 billion trillion stars make their home in the observable universe.” That is impossible to conceive. “A comparison may make it more comprehensible: if that same number of dimes were packed together as densely as possible and piled 1,500 feet high (as high as some of the world’s tallest skyscrapers), they would cover the entire North American continent.”
How should we understand the relationship between God’s sovereignty and our responsibility to evangelize? J.I. Packer’s book, Evangelism and the Sovereignty of God, is a helpful book for those considering this important question.
God’s Sovereignty and our Responsibility
Packer gives various examples of the sovereignty of God. He points out that just by praying to God we acknowledge His sovereignty. Packer points out that God’s sovereignty and man’s responsibility are taught side by side in Scripture. And “far from making evangelism pointless, the sovereignty of God in grace is the one thing that prevents evangelism from being pointless. For it creates the possibility—indeed, the certainty—that evangelism will be fruitful.”
God’s sovereignty is a great means of encouragement to us in our evangelism. Packer helpfully says that in our evangelism we
have every reason to be bold, and free, and natural, and hopeful of success. For God can give His truth an effectiveness that you and I cannot give it. God can make His truth triumphant to the conversion of the most seemingly hardened unbeliever. You and I will never write off anyone as hopeless and beyond the reach of God if we believe in the sovereignty of His grace.
So, we are responsible for sharing the gospel but God is sovereign. A proper understanding of God’s sovereignty and our responsibility is important and practical. It is important for us to realize, as Packer says, that “it is God who brings men and women under the sound of the gospel, and it is God who brings them to faith in Christ. Our evangelistic work is the instrument that He uses for this purpose, but the power that saves is not in the instrument: It is in the hand of the One who uses the instrument.” So, “the belief that God is sovereign in grace does not affect the necessity of evangelism.” Will Metzger, in agreement with Packer says, “We should not consider… sovereignty and responsibility as enemies but rather see them the way the Bible does—as friends!” So, God’s sovereignty and man’s responsibility may seem at odds but they are really not, although we may not understand. We must remember that the secret things belong to the LORD but the things that have been revealed belong to us that we may do what God has called us to do (see Deut. 29:29).
