Psalm 62
David professes his confidence in God and encourages himself to wait on God.
These words are applied to God; rock, hope, shelter, refuge, strength, salvation, strong tower, fortress, help, deliverer.
These words are applied to man; leaning wall, tottering fence, nothing, a breath.
Quite a contrast!

 “Surely you will reward each person according to what he has done.”

These are not the rewards we take to the earthly bank. These are deposited in the heavenly treasury.

1 Cor 3:11-14
For no one can lay any foundation other than the one already laid, which is Jesus Christ. If any man builds on this foundation using gold, silver, costly stones, wood, hay or straw, his work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each man's work. If what he has built survives, he will receive his reward.
Made a deposit in the heavenly treasury today?

Psalm 64

Even though our enemies may conspire and scheme against us, we need not worry about the arts of self defense, but may leave the future of our enemies in His hands. 

Psalm 69
This is another prophetic psalm, lived by David, but a prophecy of the Messiah.  Psalm 69:14-20 describe His Gethsemane experience (Matthew 26:36-45). Psalm 69:21 describes the cross (Matthew 27:34-48.  David says, "zeal for your house consumes me."  Does our zeal for the Lord consume us? 
David mentions putting on sackcloth.  Do we figuratively "put on sackcloth" and ask God to reveal our sins to us so that we can repent?   The last few verses of this psalm are layered prophecies, yet to be fulfilled in our future. 

In verses 30 and 31 of Psalm 69 David says that praising Him in song and thanksgiving pleases Him more than our sacrifices.  It has been our experience (Phil and Patti) that whenever a person may experience "sinking in the miry depths where there is no foothold" is when God is looking for us to praise Him.  It is then that He does His best work in us!
