Yes, just as you can identify a tree by its fruit, so you can identify people by their actions (Matthew 7:20, NLT).

In context, Jesus speaks of false prophets. His point is simple. Whether you are a prophet, a pastor, a bishop, or an ordinary professor of faith in Jesus, your actions reveal the truth about you.  How can you tell an apple tree from a pear tree? You look at the fruit. By the same token, how can you tell a real Christian from a hypocrite? You look at their actions (fruit). What do their lives produce?

True Christians strive to be faithful to Jesus. They live to honor His name. Their lives are full of good works. They are loyal to His church. They are quick to forgive. They do what they can to spread the news that Jesus saves. They understand that their good works are not the cause of their salvation. Faith in Jesus is the root cause of salvation. Good works are simply the fruit produced by faith.

A true Christian is not known by what he or she says but by the fruit produced in their lives. Christians do not work hard to create good works. Instead, they trust in Jesus, and He works in and through them to produce Christian fruit. They simply do what comes supernaturally. 

Father God, I thank You that Your free grace has touched my life. I thank You for the gift of eternal life. Please grant that I may always be sensitive to the leading of the Holy Spirit, that I may produce good fruit for the Kingdom of God, for Jesus’ sake, Amen.
