This is a faithful saying, and these things I want you to affirm constantly, that those who have believed in God should be careful to maintain good works. These things are good and profitable to men. (Titus 3:8)
In Titus 3:8, “This is a faithful saying”, Paul is emphasizing that what he has written (Titus 3:4–8) is a trustworthy statement, one that is central to the Christian faith. There are four other places in the Pastoral Epistles where Paul labels his teaching as a faithful saying (1 Timothy 1:15, 3:1, 4:9; 2 Timothy 2:11–13). It is significant that the faithful saying in Titus includes an admonition to maintain good works, the theme of the letter. These things are good and profitable: This emphasizes the practical benefit of good works.
There are many scriptures in the Holy Bible where it teaches us that as Christians we are to do "good works" which then glorifies God and at the same time it shows the world (unsaved) that we are followers of Jesus (John 10:32; Acts 9:36; Romans 13:3; Ephesians 2:10; 1 Timothy 2:10, 5:10, 5:25, 6:18; Titus 2:7; 1 Peter 2:12).
Jesus Himself makes it clear in the following scripture of how important it is for His followers to go out and do "good works" that glorifies God:
Let your light so shine before men, that they may see your good works and glorify your Father in heaven. (Matthew 5:16)
Can you hide a city that is sitting on top of a hill? Its light at night can be seen for miles. If we live for Christ, we will glow like lights, showing others what Christ is like. We hide our light by: (1) Being quiet when we should speak. (2) Going along with the crowd. (3) Denying the light. (4) Letting sin dim our light. (5) Not explaining our light to others. Or (6) Ignoring the needs of others. Be a beacon of truth – don’t shut your light off from the rest of the world.
Now we must understand that "good works" has nothing to do with your salvation… we are saved by the grace of God and our faith in Jesus alone... and not by what we can do. When we are "born-again" and become followers of Jesus we want to emulate our Lord and Master. And as you can see from the scriptures above... Jesus Christ commanded us to let our "light" shine before men, that they may see our "good works" and glorify God.
Father God, it is my prayer today that whatever I say or do will bring glory to your name. I pray this all in Jesus' name. Amen.
