In Joshua 1:6-9 God spoke to Joshua the following words:
6 Be strong and of a good courage: for unto this people shalt thou divide for an inheritance the land, which I sware unto their fathers to give them. 7 Only be thou strong and very courageous, that thou mayest observe to do according to all the law, which Moses my servant commanded thee: turn not from it to the right hand or to the left, that thou mayest prosper withersoever thou goest. 8 This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success. 9 Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the Lord thy God is with thee whithersoever thou goest.
Those words spoken thousands of years ago remain true even today. Joshua, strong and of good courage, lead God’s people across the Jordan River and into the promised land. We, strong and of good courage, are to lead God’s people into the promised land – Matthew 28:18-20:
18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. 19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
God has set before each of us the world and we are to be strong and of a good courage. A strength and good courage built on our faith in the strength of God. A strength and good courage built on our faith in the scriptures. A strength and good courage built on the presence of God in our life. However you reach out to the world to evangelize to the lost be strong and of a good courage.
