Just like a good tree will bear good fruit and a bad tree will only produce poor fruit (Matthew 7:16-17)…our walk with the Lord is all about fruit production. You may have a hundred Bible verses memorized, but if you never put them into usable application…what good are they? Here James is saying, I will show you my faith by taking what I learned and witnessed about the Lord Jesus Christ and put it into practical action. In other words, a work-less faith is a worthless faith when at the end of the day there is no fruit (good works) to show for it.
In this letter to Titus, Paul is encouraging him to exhort the early Church in Crete to, “do what is good.” Now earlier in this Chapter Paul plainly lays out what this means for Titus…submit to authority, be obedient, peaceable, considerate, and humble. So how does this apply to us today? When we put our faith in Jesus Christ we become His hands and feet to not only proclaim the Good News of the Gospel to the world, but to represent Him to others. And in doing so emulating His character and attributes. So hopefully when people look at us-they see Jesus.
