Joshua 1:6-9 says "Be strong and courageous, for you will lead my people to possess all the land I swore to give their ancestors. Be strong and very courageous. Obey all the laws Moses gave you. Do not turn away from them, and you will be successful in everything you do. Study this Book of the Law continually. Meditate on it day and night so you may be sure to obey all that is written in it. Only then will you succeed.
PS, this is why I think cross generational relationships are so essential in life. The maturing generation has so much wisdom to offer, the emerging generation has so much courage to bring to the table.
