One of my favorite Bible verses about confidence is "I am sure of this, that He who started a good work in you will carry it on to completion until the day of Christ Jesus." The Lord will perfect that which concerneth me: thy mercy, O Lord, endureth for ever: forsake not the works of thine own hands. When the poor and needy seek water, and there is none, and their tongue faileth for thirst, I the LORD will hear them, I the God of Israel will not forsake them. [ 18 ] I will open rivers in high places, and fountains in the midst of the valleys: I will make the wilderness a pool of water, and the dry land springs of water.
So God gave His assurance to His young prophet: “Be not dismayed at their faces” (Jeremiah 1v17) – even though those faces would be full of rage, spitting venom and hatred at him. “Behold I have made thee this day a defenced city” (verse 18) – You, Jeremiah, not the city of Jerusalem.
“I have chosen you and have not cast you away.” (Isaiah 41:9) The tribulations in this world that confronts you might cause you to doubt whether God has forsaken you. Some weakness or the dreadful hidden sins in life would have misled you into the caves of doubts and fears and stopped you from clinging on to God’s calling.
