God is Omnisapient (all-wise)
Another good definition of wisdom is "that perfection of God whereby he applies His knowledge to the attainment of His ends in a way which glorifies Him most." (Louis Berkhof).
Once again we see that God is not like humans. Humans can be knowledgeable but not very wise and they can be wise but not very knowledgeable. God is both, fully and completely. All knowing and all wise.
The awesome news for us is that the goals of God for his glory also includes our good. (Rom. 8:28). We can be sure that God's decisions which will accomplish ends that bring him most glory are also decisions that are in his creatures best interests.
There are no passages that say, "God is all-wise", but there are plenty that talk about the wisdom of God (e.g. Jude 25, Rom. 16:27, 1 Tim. 1:17, Job 9:4).
The wisdom of God when looked at with his omniscience, omnipresence, and omnipotence is wonderful news that shows a great BIG God who knows all things, is everywhere at once, has the power do all that he pleases, and has the wisdom to bring about his perfect goals in the perfect ways.
Lastly, it is encouraging that not only is God all wise, but he also is willing to to share his wisdom with us that we may be wise (Proverbs 2:6-7, James 1:5). For all matters pertaining to life and godliness (which is everything) through his divine power and the knowledge of him through His word we can handle any situation and problem (2 Peter 1:3).
