Joy?

"Behold, God is my salvation; I will trust, and will not be afraid; for the LORD GOD is my strength and my song, and he has become my salvation."
With joy you will draw water from the wells of salvation.
And you will say in that day: "Give thanks to the LORD, call upon his name, make known his deeds among the peoples, proclaim that his name is exalted."

Isaiah 12.2-4

With God as our only means of being saved, we are eternally safe. We cannot lose our salvation because it rests in his well and his well is always stocked and ever overflowing. We can never do anything so bad that we are beyond his reach, his well runs deeper than the betrayal of any sin we could commit. It is therefore with eternal joy that we draw our water. It is with eternal joy that we confess our wretchedness, knowing that he will change us to be like his one perfect son. It is with joy that we trust him through all that life could throw at us, knowing that the most important thing is taken care of, our anchor is secure and our well will never run dry, therefore we are never afraid. A city with impenetrable walls and constant supply need never fear attack. They simply need to sit put, not do anything stupid and keep going and drawing every thing they need from their source. We must do the same. We must look to God as our only means of salvation and therefore our only means of security. We must not look to anything outside of him to fill any of our eternal needs, for they never could and would only bring pain flowing from rebellion. We have it all! How rarely we see it.
