Songs I wish I could sing

But as for me, I will always have hope; I will praise you more and more.
My mouth will tell of your righteousness, of your salvation all day long, though I know not its measure.
I will come and proclaim your mighty acts, O Sovereign Lord; I will proclaim your righteousness, yours alone.
Since my youth, O God, you have taught me, and to this day I declare your marvelous deeds.
Even when I am old and gray, do not forsake me, O God, till I declare your power to the next generation, your might to all who are to come.
~ Psalms 71:14-18 (NIV)
