Genesis 22:1 Now it came to pass after these things that God tested (Hebrew word len-a-sot, to try) Abraham, and said to him, "Abraham!" And he said, "Here I am."
John 6:5-6 Then Jesus lifted up [His] eyes, and seeing a great multitude coming toward Him, He said to Philip, "Where shall we buy bread, that these may eat?" But this He said to test (Hebrew word, lenasot, to try) him, for He Himself knew what He would do.
James 1:2-4 My brethren, count it all joy when you fall into various trials (nisayon (noun form of lenasot)), knowing that the testing of your faith produces patience. But let patience have [its] perfect work, that you may be perfect and complete, lacking nothing.
The testing of Abraham's faith was repeated by YHVH throughout the patriarch's entire life. The tests grew greater as his life advanced, and through every one, whether Abraham passed or not, YHVH proved Himself to be his friend over and over again. Every test or "trial" involved a serious challenge or threat in which Abraham had to trust that the LORD knew what He was doing, asking, or requiring, and that His goodness and faithfulness were unquestionably reliable.
This type of testing or trying of faith is displayed throughout the Scriptures. In an entirely different setting Yeshua (Jesus) asked His disciple Philip a question, "Where shall we buy bread, that these may eat?" The purpose of the question was simply to try Philip's faith. The Hebrew, "lenasot" "to try, or test", in the Greek is "pi-ras-mos", which carries an interesting connotation: "proving by experiment".
James, the Lord's brother, speaks of the "testing of our faith", as well. Though we often think of this testing in negative terms, James exhorts us to "count it all joy", never mind that it's virtually certain there will be little pleasure in the experience of any trial. The fact is that trials function as experiments, and experiences, which serve to prove and improve our faith. In the Hebrew New Testament (Brit Chadasha) the word for "trial" is "ni-sa-yon", which also happens to be the word for "experience" and "experiment".
So the trials we experience are literally, experiments upon our faith. And while it is clear that God Himself does not tempt us, we also know that He allows our faith to be proven by experience, and experimentally verified. Faith is not based on experience; it is based on revelation from God. But it's genuineness is tested by experience. And it ought to be growing through every trial, producing a deeper comprehension of God's faithfulness.
Your faith is being proved to be genuine through testing and trial; experimentally and experientially, just as was the faith of Abraham, Philip, and every true saint of the Lord. For while faith is the substance of things hoped for, the evidence of things not seen -- it will be proven in, by, and through the very hard experiences and realities of your life. This is not accidental but very much in the plans and purposes of the Lord.
