Paul makes a couple of simple statements in Philippians chapter 1 that are a great reminder for us as Christians.
We should strive to grow in knowledge and understanding so that we understand what really matters most in order to live pure, and blameless lives. The thing that matters most is that we let our love overflow more and more.
He also reminds the Philippians to remain filled with the fruit of their salvation which is the righteous character produced in your life by Christ. This is what brings glory, honor, and praise to God.
The fruit of your salvation is your righteous character, and the biggest evidence of that character is how you treat other people. Is love spilling out of you? The opposite of love is fear. As people we generally treat people inappropriately when we are afraid of them in some way. Perfect love casts out all fear.
Let your love flow without fear, and let your righteous character shine!
God is for you, and I am for you. Let there be no fear in you.
