In the book of Proverbs, we learn much about the advantages of having wisdom; for example, in Proverbs 1:33 (KJV), we are told that with wisdom we: “shall dwell safely, and shall be quiet from fear of evil”. In Proverbs 3:13-18 we read that wisdom is worth more than money and jewels and it leads to long life, finances, honour, joy and peace. Proverbs chapter 4 gives us many more blessings of wisdom.
That being the case, how do we get wisdom? The book of Proverbs was written so we could learn wisdom (Prov 1:2) so that’s a good place to start. There is a big clue in Proverbs 9:10: "the fear of the Lord is the beginning of wisdom". "The Lord giveth wisdom" (Prov 2:6), so there is another big clue as to how to obtain wisdom.
If we spend quality time with God his wisdom will be imparted to us. This is confirmed in 1 Corinthians 1:30, where it says that God made Jesus to be our wisdom. The apostle Paul taught us that all the treasures of wisdom are found in God (Col 2:3). Finally, in the epistle of James 1:5 we are assured us that we can simply ask God for wisdom and he will give it generously (James 1:5).
So, take God at his word and if you need wisdom for a particular situation then ask for it, but more importantly as you spend more and more time with God you will find his wisdom becoming a part of you, kind of like osmosis.
