“For you, O God, have tested us; you have tried us as silver is tried.” (Psa 66:10)
God tests people. It is obvious, though, that His testing is different from the testing man does when man tests either God or his fellow man. When God tests, He already knows the outcome of the test, whereas, when man tests, he tests to find things out. Israel tested God to find out whether or not God was with them (Exo 17:7). God tested Abraham so as to demonstrate that He, God, was faithful and kept His promises. When Abraham prepared to offer Isaac, he proved that he trusted God and obeyed His command, knowing that God means what He says and says what He means, and that everything was possible for God, even raising Isaac from the dead, so that His promise would still be fulfilled. This faith was counted to Abraham as righteousness, and serves as an example for us today.
“And he [Abram] believed the LORD, and he counted it to him as righteousness.” (Gen 15:6)
Note that Abram “believed God” – not “believed in God”, as some translations would have it. It is a rather straight forward and practical thing here: God promises Abram that his very own son shall be his heir and that his offspring will be numerous, and Abram believes that what God says is true.
In other words, Abram trusted, and obeyed:
“And the angel of the LORD called to Abraham a second time from heaven and said, “By myself I have sworn, declares the LORD, because you have done this and have not withheld your son, your only son, I will surely bless you, and I will surely multiply your offspring as the stars of heaven and as the sand that is on the seashore. And your offspring shall possess the gate of his enemies, and in your offspring shall all the nations of the earth be blessed, because you have obeyed my voice.” (Gen 22:15-18)
Abraham’s behavior serves as an example in the New Testament:
“By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was in the act of offering up his only son, of whom it was said, “Through Isaac shall your offspring be named.” He considered that God was able even to raise him from the dead, from which, figuratively speaking, he did receive him back. (Heb 11:17-19)
So when God, the Almighty and All-knowing God, tests a people or a person, He does it to reveal something of Himself to His people and to the nations, at least that’s one of the reasons. In another instance we see God testing people to separate them (Jdg 7:5-7), but more often, He tests the minds and hearts, refines people in the fire, to reveal His glory to them, and us, in the way He deals with those that are faithful to Him.
“And I will put this third into the fire, and refine them as one refines silver, and test them as gold is tested. They will call upon my name, and I will answer them. I will say, ‘They are my people’; and they will say, ‘The LORD is my God.’” (Zechariah 13:9)
The reaction of the tested people in the bible is significant because, whether they stand or fail the test, God does to them as He promised, depending on the obedience, the love they show to Him. God is faithful and His love is steadfast, for those who walk in His way and listen to His voice.
“All the paths of the LORD are steadfast love and faithfulness, for those who keep his covenant and his testimonies.” (Psa 25:10)
The bible is not about you and me, it is not about people in the first place. First and foremost, the bible is about God. He reveals Himself in Scripture, reveals what He deems good for us to know about Him, and reveals, more importantly, what He wants us to do: Have faith and be faithful, that means, believe God, trust that God means what He says and says what He means, and obey His commandments, statutes and precepts. If you do that, He says, it will be counted to you as righteousness.
