The quote in the image is hypothetical and overstated to illustrate a point. Throughout church history, God’s people have looked to the whole of Scripture to inform belief–not single proof texts. Part of that process is using reason to infer truth. Ergo, we find the doctrine of the Trinity woven throughout Scripture like a resplendent, intricately-detailed tapestry.
The 1689 London Baptist Confession of Faith in Modern English, chapter 1.6 begins, “The whole counsel of God concerning everything essential for his own glory and man’s salvation, faith, and life is either explicitly stated or by necessary inference contained in the Holy Scriptures. Nothing is ever to be added to the Scriptures, either by new revelation of the Spirit or by human traditions” (emphasis mine).
In using logic and reason to determine good and necessary consequences from God’s Word, we are simply practicing the interpretive technique modeled by our Lord in Mark 12:24-27:
24 Jesus said to them, “Is this not the reason you are wrong, because you know neither the Scriptures nor the power of God? 25 For when they rise from the dead, they neither marry nor are given in marriage, but are like angels in heaven. 26 And as for the dead being raised, have you not read in the book of Moses, in the passage about the bush, how God spoke to him, saying, ‘I am the God of Abraham, and the God of Isaac, and the God of Jacob’? 27 He is not God of the dead, but of the living. You are quite wrong.”
The passage to which Jesus refers does not explicitly state that there is indeed a resurrection, which the Sadducees rejected. But that doesn’t stop the Son of God from using God’s message to Moses to demonstrate the logical, reasonable truth of the resurrection. God IS the God of the living, consequently we will be resurrected: those who reject God to eternal judgement, and those in Christ to eternal life.
