Trust

"Don't quit. Don't give up." That's the message we need to hear. 

I think of Isaiah 43:1b-2: "Fear not, for I have redeemed you...; I have called you by your name; you are Mine. 

When you pass through the waters, I will be with you, and through the rivers, they will not overwhelm you. When you walk through the fire, you will not be burned or scorched, nor will the flame kindle upon you." 

And let us not be weary in well doing: for in due season we shall reap, if we faint not.
