Fruits - a Christian perspective
How can you tell who is a Christian? We can't judge what's in people hearts, but we can observe the "fruit" of their behavior. A life that's dedicated to Christ will inevitably produce good fruit, whereas a sinful life will inevitably produce bad fruit.
Fruits of the Spirit in the Bible: Galatians 5:22-23
What should a Christian's life look like? The "fruits of the spirit," listed in this passage, are the characteristics that should define the lifestyle and behavior of anyone who follows Christ. They're godly traits that are the natural result of a life devoted to Jesus.
