Every day it seems that a situation arises that brings with it that question. How far can I trust Him. I would like to turn your attention to the Bible character who became known as the father of the faithful- Abraham. We never are secure from trials. In Hebrew, to tempt, and to try, or to prove, are expressed by the same word.
Every trial is a temptation, and tends to show the condition of the heart, whether holy or unholy.
God does not tempt us to destroy us. So God proved Abraham, not to draw him to sin, as Satan tempts. God would not in any case have human sacrifices used. Yet He calls Abraham to do so. Take Isaac, that son whom thou lovest.
