How to have that wisdom from above? And, what is that wisdom from above that they are talking about? Wisdom from above has its origins with God, not man. Its character is heavenly and not earthly. It is God's gift and must be received from Him. There is no real surprise that true Christians seek their wisdom from above and not from man.
People in our lives may sometimes suggest we do what seems most gratifying or practical in the moment. But, there is a difference between worldly and spiritual wisdom (1 Cor. 2:6-7). Wisdom from above is first pure, then peaceable, gentle, willing to yield, full of mercy (James 3:17). When others are urging us to take a certain course of action, we can invite God to influence our response. One is truly wise who gains his wisdom from above.
Jesus Christ is our wisdom. The Word of God is our wisdom. It is only from the scriptures that we can become wise unto salvation. This wisdom can be accentuated through believing prayer. If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him (James 1:5)
