2 Peter 1:5-7 ...make every effort to add to your faith goodness; and to goodness, knowledge; and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness; and to godliness, brotherly kindness; and to brotherly kindness, love (NIV).
I. Why is the character of a Christian important?
Our character always defines us. As a Christian, our character should define us as Christians. They should prove who we are. How can we preach change to others if we haven’t changed ourselves? How can we preach love to others when we have none ourselves? Basically, how can the Spirit of God be in us if we have no characteristics of the Spirit? Jesus said it best in Luke 3:8, "Produce fruit in keeping with repentance." (NIV)
If you say you changed an apple into an orange, but it still looks like an apple, smells like an apple, tastes like an apple and has apple seeds in it, guess what? You didn't change it into an orange! It's still an apple. Same with a Christian, if you say you've changed and you still act like a sinner, talk like a sinner, hang out with sinners and still like to sin, guess what? You didn't change!
Why do people shy away from Christianity? Because too many people "talk the talk", but don't "walk the walk".
The proof is in the fruit!
