Those that have command as a position, command; having been given the authority to, command.  Ultimately, the command is given by God, as, “It is God alone who judges; He decides who will rise and who will fall.”

“Long ago God spoke many times and in many ways to our ancestors through the prophet, and now through His Son.”  But He also spoke to some directly, earlier.  To the appointed successor of Moses, God spoke directly, succinctly, “This is My command—be strong and courageous!  Do not be afraid or discouraged.  For the LORD your God is with you wherever you go.”” Yes to strong and courageous. No to fear and discouragement; and therefore yes to trust and obey and hope and action!
Father, thank You for such a command that rolls forward to each of us to perform as Your will in life, believing Your Word (Son) and words, trusting You as Sovereign.
As Jesus has commanded, “Go!” in His full power and Spirit, building up others to trust Him in the same way.  “Encourage each other and build each other up,” knowing He is with you wherever you go.
