In Joshua 1: 9, God exhorts Joshua saying:
Look that I send you to try to be brave; Do not fear or faint, for Jehovah your God will be with you wherever you go.
If God gives a person a responsibility, it is necessary to assume the commitment with great value. Every Christian must understand that God has not given him a spirit of cowardice, but of power and self-control.
In each task that God can assign, two enemies will be presented to overcome, which are: fear and discouragement. These emotional enemies cannot do anything in your life, only you allow it. The spirit of self-control that God has placed within you will make these emotional factors (fear and discouragement) under your will; It means you have mastery over fear and discouragement.
Joshua understood that in order to succeed in the task that God had entrusted to him, it was necessary to neutralize fear and to trust fully in God, who had promised him, that in the same way that he was with Moses, he would be with him.
Joshua internalized the requirement to be brave to be able to introduce the people of Israel into the promised land, and God himself would be responsible for defeating the armies of pagan nations and surrendering the land to the people of Israel.
Joshua did not hesitate to assume the challenge God gave him, after the death of Moses.
On several occasions, God exhorted Joshua not to be afraid and to trust that God was with him; He just had to develop a spirit of courage and undertake the conquest of the promised land.
If God has given him the responsibility of shepherding a church, or a missionary responsibility to a nation that is not his own, or any other responsibility in the ministry; Do not be afraid or discouraged by the new demands of God, because God promises to support you and give you victory in all stages of life.
Be determined to develop within yourself a spirit of courage so that it becomes a useful instrument in the hands of God.
