Jeremiah 1:17
But you (Jeremiah), gird up your loins (in preparation)! Get up and tell them all which I command you. Do not be distraught and break down at the sight of their (hostile) faces, or I will bewilder you before them and allow you to be overcome.
It takes faith to witness to people in Jeremiah’s day and ours. Not everyone wants to hear the truth of the gospel, and some will reject it. When we have courage and wisdom, we will be able to reach people for God. God is more than able to lead us to talk to people about Him. Be of good cheer; Jesus has been rejected more than we have.
