A lot of people have different concepts of what it means to become a Christian. To some people, being a Christian means that you are expected to be at church on Sunday. But being a Christian is more than just attending worship services, more than giving of your means, and more than just keeping a pure tongue, although all these are essential for the person to live pleasing to God. Being a Christian also means leading someone else to Christ.
Proverbs 11:30 “The fruit of the righteous is a tree of life”, a powerful proverbial statement of King Solomon means a lot to anyone who is a right-standing believer in Christ Jesus.
The statement establishes that believers have mouths with which to communicate the Gospel. We also have the privilege to perform certain things for the Kingdom. We are God’s representatives (ambassadors) here on earth.
You don’t have to make any noise about yourself, it is your deed (works) that would depict who you are. Jesus in you is the hope of glory.
The statement is referring to the expectation of God from a believer. God has already made the believers be a fountain from which life will flow. He is supposed to demonstrate the fruit of the Spirit as contain in Galatians 5:22-26.
It is advisable to talk to God first about someone before sharing the gospel with them. Pray about the person, then ask the Holy Spirit to help you communicate.
The question is; how is your life preaching the gospel?
