Joshua is one of the greatest characters in all of the BIble. He was Moses' protege and chosen to lead God's people courageously into the promised land. 

There is a great hymn with these lines "Onward Christian Soldiers Marching as to war with the cross of Jesus going on before" and the theme running through the pages of Joshua is moving Forward. Forty years the children of Israel had to wander in the wilderness and wonder what could have been, what should have been, but Joshua because of his commitment and obedience to God would get to see the Promised land. 

What if in 2023 the people of God marched not half hearted, not semi-Christian, no looking back, everyone put everything all in for Jesus! In Joshua chapter 1, God tells Joshua three times to Be Strong and Very Courageous and anytime God reiterates something it is important!
