Having your conduct honorable among the Gentiles, that when they speak against you as evildoers, they may, by your good works which they observe, glorify God in the day of visitation (1 Peter 2:12 NKJV)
Sometimes, believers relegate good works to the background of their Christian Faith but the Bible clearly tells us that unbelievers can glorify God because of our good works. The fruits of the Holy Spirit manifesting through us can also attract, and draw men towards Christ.
Filled with the fruit of righteousness that comes through Jesus Christ—to the glory and praise of God. Philippians 1:11
For God is working in you, giving you the desire and the power to do what pleases him. Philippians 2:13
Unbelievers will take us more seriously if we practice what we preach, after all, the summary of the gospel is to love and forgive others the way Christ loved and forgave us. The gospel is all about believing and obeying. We must believe that the blood of Jesus set us free and we must bear and manifest the fruits of the Holy Spirit which is the good works of Christ through us.
May great grace be upon us in Jesus name.
