Nehemiah 8:10 is an encouraging scripture that says, "…Do not sorrow, for the joy of the Lord is your strength" (AMP). God wants us to stay joyful no matter what difficulties we face in life, because His joy is our strength. Simply put, it's the fruit of joy that strengthens us to go through whatever we have to deal with and make it to the end result. That's why, as Christians, joy should be our normal mood.
Paul was determined to enjoy the journey no matter how many potholes were in the road. In Colossians 1:11, he wrote, "[We pray] that you may be invigorated and strengthened with all power according to the might of His glory, [to exercise] every kind of endurance and patience (perseverance and forbearance) with joy" (AMP). Our joy is a weapon. It gives us the ability to not only endure difficulties, but to enjoy life in the midst of them.
