62 Truly my soul waiteth upon God: from him cometh my salvation. 2 He only is my rock and my salvation; he is my defence; I shall not be greatly moved.
3 How long will ye imagine mischief against a man? ye shall be slain all of you: as a bowing wall shall ye be, and as a tottering fence. 4 They only consult to cast him down from his excellency: they delight in lies: they bless with their mouth, but they curse inwardly. Selah.
5 My soul, wait thou only upon God; for my expectation is from him. 6 He only is my rock and my salvation: he is my defence; I shall not be moved. 7 In God is my salvation and my glory: the rock of my strength, and my refuge, is in God. 8 Trust in him at all times; ye people, pour out your heart before him: God is a refuge for us. S 9 Surely men of low degree are vanity, and men of high degree are a lie: to be laid in the balance, they are altogether lighter than vanity.10 Trust not in oppression, and become not vain in robbery: if riches increase, set not your heart upon them.
11 God hath spoken once; twice have I heard this; that power belongeth unto God.12 Also unto thee, O Lord, belongeth mercy: for thou renderest to every man according to his work.
I've noticed that there are many people who do not like to be still or silent. They can't handle just waiting and being still. I once bet a young man that he could not stay still for 3 minutes. I didn't lose my bet. He could not be still! This problem with not being able to wait leads people sometimes to act impulsively and to rush into situations and to act when they should have waited. It leads others, even christian people, to sometimes act without praying about their decisions and choices which leads to terrible consequences.
There are various words used in this psalm about how God is a refuge or stronghold or place of rest. The visual that many people would have had is one of a walled city sitting on a high place completely fortified with towers and gates. It is a place of protection from the elements and enemy. Scripture repeatedly gives us this image of God as one who can be relied upon to protect and provide in times of trouble. Notice that it doesn't say that troubles will not come, but that God will be with us through those trouble. It said that about Joseph in the old testament several times. Even when he was sold into slavery by his brothers and ended up in prison God was still with him. Genesis 39:21,23
I have also noticed that many times even believers put their trust in other people or things instead of God when trouble comes including myself sometimes. I think this is part of our sin nature to have a tendency towards self reliance and self confidence instead of dependence on God. We have a tendency to trust in our own clever ability or training or skill rather than just waiting on God. This doesn't mean that we always need to be passive. It does mean that we ultimately should trust in God to take care of us and provide for our needs.
Psalm 62 is what is called a "song of confidence" and is a mix of both uplifting words of confidence and alternates with some words about persons who are evil and trust in falsehood or the KJV uses the word lies. Ulitmately, this psalm is about who we put our trust in. In verse 8, the Psalmist concludes that he can trust in God and therefore he will "pour" out his heart to God. This is an unhindered pouring out of the heart to God without restraint.
Some other verses that speak about this is Psalm 59:17 says that God is his stronghold and God is the one who shows you lovingkindness. Psalm 37:39 God is their strength in time of trouble.
