7Only 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.
8This 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.
9Have 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. ~ Joshua 1:7-9
Read, study, and obey the Word of God.
Never fear He is with His children. His children are obedient and shall be showered with many blessings. Will those blessings come easy? No. But, as long as you are obedient: "...then thou shalt have good success."
See? Hope.
"Be strong and of good courage... the Lord thy God is with thee."
