Philippians 3:1 - "Finally, my brothers, rejoice in the Lord! It is no trouble for me to write the same things to you again, and it is a safeguard for you."
The word "rejoice" is used eight times in this short book. Seems the Philippian Christians needed the reminder to "rejoice IN THE LORD" not in circumstances. What is interesting is that Paul wrote this while in prison where his circumstances were, without a doubt, less than ideal. Here is a man, who could be discouraged, encouraging others to rejoice.
Discouragement just may be one of the most common intangible battles we face as Christians. It might be one of Satan's most used and most damaging weapons. It's easy to get discouraged ... kids don't listen, seems we have more to do than time or energy, work struggles, finances are more negative than positive - and me personally right now is my desire to live a more healthier life. Why is it that as soon as I make a commitment to eat better & exercise that circumstances come up that easily discourage me?
This is why Paul pleads with us to rejoice "in the Lord". When our focus is on Jesus, the things of this world become far less significant. Like the old hymn says... "Turn your eyes upon Jesus ... and the things of earth will grow strangely dim in the light of His glory and grace."
And...it's obvious that the Philippian Christians are just like me. They needed to hear this over and over and over and over. I need to hear this over and over and over and over. I need to be reminded continually to "rejoice in the Lord."
How does that happen? Primarily via reading the Bible. The more I read the Bible, the more I focus on Jesus and rejoice in Him. The more of His Word I put in my brain, the more of His joy and attitude I live out.
