Simeon believed. He didn’t merely exist, letting the days go by unmarked, unmindful of greater things being done in the heavens, oblivious to the work the Lord was doing to prepare the world for His coming—or even discounting the prophecies, and deciding God might not be as trustworthy as he supposed. He noted the times, and he believed the prophets who said no one is like God. No one could perceive how he works. He is beyond this time and space, and as such, he is the only One who can demand we trust him as he is.
If you search through the whole creation, could you find any like Him? Are riches, honors, pleasures, or other relationships comparable to Jesus, whom you ought to love supremely? Should not the highest good be the best object of your love? Can you love lesser things, and not the greatest good? Is not all the goodness in the creature but as a drop compared to the sea, as a candle compared to the sun, as a speck of sand compared to a mountain—when compared to the goodness that is in Jesus?
