Moses was deemed gentler than everyone else on the face of the earth by God (Num. 12:3). There was an incident that showed this gentleness of Moses vividly.

Moses climbed up Mt. Sinai to receive the Commandments of God, but when he was slow to return, the sons of Israel made and worshiped an idol in the image of calf. God's wrath was to fall on them, and Moses interceded.

In Exodus 32:32, Moses earnestly prayed for them, saying, "But now, if You will, forgive their sin and if not, please blot me out from Your book which You have written!"

As a matter of fact, Moses did not possess this gentle heart from the beginning. Moses was a Hebrew, a descendant of Israel, but he was qualified in many aspects because he was brought up as a son of a princess of Egypt. Because of this self-righteousness, one day he beat an Egyptian to death who was cruelly treating a Hebrew. Because of this incident Moses escaped with nothing. While he was living the life of the shepherd rather than a prince of Egypt, he felt and thought of the love of God and human life, and he humbled himself completely.

The most important lesson in cultivating the kind heart is that you have to humble yourself before God and cultivate the heart of goodness and love through trials given.
