I have been thinking about John Piper’s suggestion that he has set forth repeatedly in his different books, that is, being motivated by the glory of God to evangelize. I had not previously formulated this as a proper motivation for evangelism before I heard it from Piper. This is actually a very biblical idea. When one reads of Moses speaking to the Israelites prior to entering the Promised Land he mentions,
“For what great nation is there that has a god near to it as the Lord our God is ⌊to us⌋ whenever we call to Him?
8 And what great nation has righteous statutes and ordinances like this entire law I set before you today?
9 “Only be on your guard and diligently watch yourselves, so that you don’t forget the things your eyes have seen and so that they don’t slip from your mind as long as you live. Teach them to your children and your grandchildren.
10 The day you stood before the Lord your God at Horeb, the Lord said to me, ‘Assemble the people before Me, and I will let them hear My words, so that they may learn to •fear Me all the days they live on the earth and may instruct their children.’
11 You came near and stood at the base of the mountain, a mountain blazing with fire into the heavens and enveloped in a dense, black cloud.
12 Then the Lord spoke to you from the fire. You kept hearing the sound of the words, but didn’t see a form; there was only a voice.
13 He declared His covenant to you. He commanded you to follow the Ten Commandments, which He wrote on two stone tablets.
14 At that time the Lord commanded me to teach you statutes and ordinances for you to follow in the land you are about to cross into and possess.
“Indeed, ask about the earlier days that preceded you, from the day God created man on the earth and from one end of the heavens to the other: Has anything like this great event ⌊ever⌋ happened, or has anything like it been heard of?
33 Has a people heard God’s voice speaking from the fire as you have, and lived?
34 Or has a god attempted to go and take a nation as his own out of ⌊another⌋ nation, by trials, signs, wonders, and war, by a strong hand and an outstretched arm, by great terrors, as the Lord your God did for you in Egypt before your eyes?
35 You were shown ⌊these things⌋ so that you would know that the Lord is God; there is no other besides Him.
36 He let you hear His voice from heaven to instruct you. He showed you His great fire on earth, and you heard His words from the fire.
37 Because He loved your fathers, He chose their descendants after them and brought you out of Egypt by His presence and great power,
38 to drive out before you nations greater and stronger than you and to bring you in and give you their land as an inheritance, as is now taking place.
39 Today, recognize and keep in mind that the Lord is God in heaven above and on earth below; there is no other.
40 Keep His statutes and commands, which I am giving you today, so that you and your children after you may prosper and so that you may live long in the land the Lord your God is giving you for all time.” Deuteronomy 4:1-14, 32-40 HCSB
This is something that born again Christians should genuinely consider. Guilt does not work well as motivation. Yet, every one of us is very inclined to share with others about magnificent moments in life: good deals on cars, insurance, groceries, clothes, etc… Yet, born again Christians have a relationship with the one true God through faith in Christ’s substitutionary atonement. This is truly powerful motivation to speak to the nations about the great God who has ransomed us through His Son. Consider living your life motivated by the greatness which belongs to the God of the Bible.
