The whole story reveals all of the truth; not standalone snippets. This doesn’t mean standalone snippets are not true. It means until the whole story is available for consideration, the details cannot be compared to each other in totality so that the whole truth can be known (Proverbs 18:13).
It’s kind of like when a parent asks their child if they’re telling the whole truth. A little here without a little there leaves us without the sum total, right?
The scriptures are a source of record even to atheists, but to be fully useful, even to theists, the scriptures must become a source of truth. This only comes by allowing the entirety of the Bible to tell the entirety of God’s will. This is like comparing puzzle pieces sitting in a box to puzzle pieces that have been placed together.
Truth comes from totality – plain and simple. The totality of God’s will for this life has been made known (2 Peter 1:3-4; Jude 1:3) but to understand this revealed will we must look at the big picture … all of the puzzle pieces must be joined in a non-contradictory way if you will (2 Timothy 2:15-19; Matthew 4:4-7; Luke 24:27).
When all things necessary have been provided, the only thing left to do is actually use all of the things provided! And this we must do to receive the totality of the knowledge from him who graciously provides all things (2 Timothy 3:14-17; Deuteronomy 29:29; 30:11-14; Romans 10:6-8; 11:33-36; 12:1-2; John 7:17; 1 Corinthians 2:9-16).
“The sum of your word is truth, and every one of your righteous rules endures forever.” (Psalm 119:160 ESV)
