Moses is the most important leader of the people of God in the Old Testament. He is an example for us of servant and leader of God. Our Lord needs, principally, servants in his Kingdom. Moses doesn't search to be a leader, God was calling him. In this incident with his brothers, it is evidence three characteristics very important and necessaries for us today, if really we want to show the glory of God into the world.
I. Humble, v. 3
A. "Now Moses was a very humble man, more humble than anyone else on the face of the earth"
B. It is the quality number one in the servant's life. It is the base of the ministry and the Christian life.
C. The Lord Jesus said: "Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls" Mt 11:29
D. We need to learn to be humble of heart, because it is not our human nature.
E. The humble person's fruit is to be tolerant with all people. This was necessary in the pilgrimage at the desert of the people of God.
II. Faithful, v. 7
A. "But this is not true of my servant Moses; he is faithful in all my house" Cf., He 3:2; "He (Jesus) was faithful to the one who appointed him, just as Moses was faithful in all God's house." This declaration is from God, is not human interpretation!!! That's very important.
B. "Moses was faithful as a servant in all God's house, testifying to what would be said in the future" He. 3:5.
C. He is the hero of the Christian faith in the New Testament, He 11:23-28. Revelation talks about of Moses as "the servant of God" 15:3b.
D. As result, the faithful is the life way of a humble heart.
E. The admonition of God for his Church forever is: "Be faithful, even to the point of death, and I will give you the crown of life" Rev. 2:10c.
III. Mercy, v. 13
A. "So Moses cried out to the Lord, O God, please heal her!"
B. Moses never judged to his sister Mary and his brother Aaron. He had compassion. Also, we have that to show the compassion of Jesus too.
C. God is the great judge. "Speak and act as those who are going to be judged by the law that gives freedom, because judgment without mercy will be shown to anyone who has not been merciful. Mercy triumphs over judgment!" Jam. 2:12-13. In this case the mercy is the primary attitude.
D. Mercy is evidence and consequence of a humble and faithful heart.
E. The true servant of God knows that the only one Lord is Jesus Christ.
Conclusion & Application
God needs servants. But is clear what is his expectative for this calling. Moses is a leader's profile in the mind of God. In this time many people want to be a leader very important, but the God's paradigm is to inverse (Cf., Luke 9:45-48 & 9:51-56). We need to make a decision now: Lord Jesus, I want to be a servant that you want in this world.
