Deuteronomy 1: 37-39
37 Because of you the Lord became angry with me also and said, “You shall not enter it, either. 38 But your assistant, Joshua son of Nun, will enter it. Encourage him, because he will lead Israel to inherit it. 39 And the little ones that you said would be taken captive, your children who do not yet know good from bad—they will enter the land. I will give it to them and they will take possession of it.
God employs His people to encourage one another. He did not say to an angel, “Gabriel, my servant Joshua is about to lead my people into Canaan—go, encourage him.” God never works needless miracles; if His purposes can be accomplished by ordinary means, He will not use miraculous agency. Gabriel would have been assigned to perform the work of Moses.
We should be glad that God usually works for man by man. It forms a bond of brotherhood and being mutually dependent on one another, we are fused more completely into one family.
Brethren, take the text as God’s message to you. Labor to help others, and especially strive to encourage them. Talk cheerily to the young and anxious enquirer, lovingly try to remove stumblingblocks out of his way. When you find a spark of grace in the heart, kneel down and blow it into a flame.
Speak a word in season to him that is weary, and encourage those who are fearful to go on their way with gladness. God encourages you by His promises; Christ encourages you as He points to the heaven He has won for you, and the spirit encourages you as He works in you to will and to do of His own will and pleasure. Imitate divine wisdom, and encourage others.
