God has been stirring His people. His people today have heard Him give this charge: “Go into all the world and preach the gospel to every creature.” (Mark 16:15)
Such an assignment seems impossible to achieve, and so it is with [human beings]. But with God it is possible -- and so the task and calling remain before us, confronting us all. Each person and church must respond.
When Jesus gave the disciples His assignment to go into all the world and make disciples of all nations, He added this promise: “And lo, I am with you always, even to the end of the age.” (Matthew 28:20) God’s call is not a program, but a Person to be followed, a Person who has given His personal command to be obeyed.
