Isaiah 12:1-3

Isaiah 12

 1And in that day thou shalt say, O LORD, I will praise thee: though thou wast angry with me, thine anger is turned away, and thou comfortedst me.

 2Behold, God is my salvation; I will trust, and not be afraid: for the LORD JEHOVAH is my strength and my song; he also is become my salvation.

 3Therefore with joy shall ye draw water out of the wells of salvation.

This scripture is a great example of what the Old Testament says about salvation through Jesus Christ. This is one I memorize and keep with me. Another note is that verse 3 almost makes it sound as if joy is a key factor in drawing upon God's grace or "living water". It shows us just how important joy is and that depression and strife should not rule our lives. However, this is not a fake joy but a real joy that comes through faith in what Jesus did for us.
