Now, while our great High Priest is making the atonement for us, we should seek to become perfect in Christ. Not even by a thought could our Saviour be brought to yield to the power of temptation. Satan finds in human hearts some point where he can gain a foot-hold; some sinful desire is cherished, by means of which his temptations assert their power. But Christ declared of himself, “The prince of this world cometh, and hath nothing in me.” [John 14:30.] Satan could find nothing in the Son of God that would enable him to gain the victory. He had kept his Father’s commandments, and there was no sin in him that Satan could use to his advantage. This is the condition in which those must be found who shall stand in the time of trouble.
