In The Scripture Alphabet of Animals (Cook, Harriet) we learn about the symbolism of Christ and the lion.  Below is an expert from her work; I hope you enjoy.

You have seen pictures of the lion a hundred times, I suppose, and perhaps you have seen it alive; would you like to know what the Bible says about it? You have heard it called the "king of beasts," because it is so strong and so bold; it is afraid of no other animal, and it is strong enough to carry away a horse or a buffalo. In the 30^th verse of the 30th chapter of Proverbs, we read about "the lion which is strongest among beasts, and turneth not away for any."

The boldness of the lion is noticed in a verse in Isaiah: "Like as the lion and the young lion roaring on his prey, when a multitude of shepherds is called forth against him, he will not be afraid of their voice, nor abase himself for the noise of them." In Proverbs, 28 : 1, you will read, "The wicked flee when no man pursueth; but the righteous is as bold as a lion."

This is true and if you will love God and trust the kind Savior, there is nothing in all the wide world of which you need be afraid. God can take care of you as he did of Daniel, even if you were shut up in a dark cave with cruel and hungry lions around you.

The roaring of the lion is very terrible, especially at night. He seems to delight to be wandering around for his prey when it is dark and stormy; then when he puts his mouth near the ground, his roaring sounds like thunder, and all the animals that hear it are full of fear. You have read of Satan, that most wicked being, who would be glad to make us as wicked as he is; the Bible says he is like "a roaring lion, walking about, seeking whom he may devour." Let us pray God to keep us safe from this roaring lion.

Christ is sometimes called "the Lion of the tribe of Judah." He is always gentle and kind to those who love him; but if we will not receive him as our Savior, the day is coming when he will meet us in judgment; then where can his enemies hide themselves.
