James 3:13 If you are wise and understand God's ways, live a life of steady goodness so that only good deeds will pour forth. And if you don't brag about the good you do, then you will be truly wise!
Wisdom involves living a life of steady goodness. It is being governed and guided by the Spirit so that you do not wander away from the holiness of God. Wisdom involves choosing to do what is right before God. Wisdom is seeking to understand the ways of God so that you may do them. Wisdom is understanding that the purpose of all knowledge is to live it.
Living a life of steady goodness means that you don't slack off in your quest for holiness of heart. You are aware of what is God's will for you and you strive to do it. Your desire is to be good and not just talk about it. Living steadily a life of goodness means that it is the way of life for you. It is how you act all the time and not just when you are in the company of other believers. It is who you are at home, work, and play.
When we live right before God, others will see it. Our lives will be enough testimony of who we are and we won't need to brag about it. It's good that we brag about the Lord and what He is doing, but it's not good to brag about ourselves as if we had anything to do with it. All of our goodness comes from the Lord. Our ability to do good deeds comes from the work of the Spirit in us. We are powerless to do good without God's help and abilities.
Wisdom is giving credit where credit is due. It is giving God the glory and honor in all things at all times. He alone is worthy of our praise.
