This is a powerful image from Spurgeon:
"Fear not is a plant which grows very plentifully in God's garden. If you look through the lily beds of Scripture you will continually find by the side of other flowers the sweet "Fear nots" peering out from among doctrines and precepts, even as violets look up from their hiding places of green leaves...As we observe the Scriptures we perceive that "Fear nots" are scattered throughout the Bible as the stars are sprinkled over the whole sky, but when we come to Isaiah we find constellations of them... Here are a few of his antidotes for the fever of fear: "Say to them that are fearful in heart, Be strong, fear not." Fear thou not, for I am with thee; be not dismayed, for I am thy God." "Fear not, I will help them." "Fear not, for thou worm Jacob." Fear not, I have redeemed thee." Fear not, for thou shalt not be ashamed; neither be thou confounded for thou shalt not be put to shame"; and so on I was going to say, "world without end." So abundant are these "Fear nots" that they grow like the king-cups and the daisies, and other sweet flowers of the meadows, among which the little children in the spring-time delight themselves. "As to gathering them all, no one would attempt the task. The bank that is fullest of these beautiful flowers is that which Isaiah has cast up; go there and pluck them for yourselves." Sermon "Fear Not" Rev. 1:17.
Spurgeon goes on to tell us we do not have to fear God's majesty in Christ.
To the sinner he says: "If you are the one man that is a little over the line of mercy, you are the very man that Jesus Christ chooses to bless, for he loves to save extraordinary sinners."
"When the Lord sends his mercy it never rains but it pours. He deluges the desert. He not only gives enough to moisten, but enough to drench the furrows. He makes the wilderness a standing pool of water, and the thirsty land springs of water. Do not, therefore, doubt the genuineness of his mercy because of its greatness."
