Joshua Chapter 18: How Long Will You Wait?

Verses 1-10 of this chapter have the most that we can learn from. The latter verses deal again with the layout of the newly inherited land by the remaining tribes. 
Joshua seems somewhat impatient with the remaining tribes, encouraging them to go and claim their inheritance of the land. It was theirs to take, however a lack of sense of ownership or inhibition was holding them back. Whatever the cause, all they needed to begin the survey of the land and thus the assignment of their lot of it, was some strong encouragement from their leader Joshua.
Likewise, we also are implored to act when we know what to do:
“For He says: “In an acceptable time I have heard you, And in the day of salvation I have helped you.” Behold, now is the accepted time; behold, now is the day of salvation.” ‭‭II Corinthians‬ ‭6:2‬ ‭
“Therefore, to him who knows to do good and does not do it, to him it is sin.” ‭James‬ ‭4:17‬
When I know that there is something I need to take hold of, a responsibility, a blessing or a duty, do I need encouragement? We all need encouragement and reminders, there is no fault in that. The true shame arrives when we do nothing despite gentle or strong reminders to act.
