We can lose our joy in the Lord when we fixate on proving, performing, pleasing…because the focus of our attention stays on us and not Christ and serving others

 I rejoice because I eagerly expect and hope that I will have nothing to be ashamed of, because through my boldness the Messiah will be exalted through me, now as always, whether I live or die. PHILIPPIANS 1:20

In this you greatly rejoice, even though now for a little while, if necessary, you have been distressed by various trials, so that the proof of your faith, being more precious than gold which is perishable, even though tested by fire, may be found to result in praise and glory and honor at the revelation of Jesus Christ;  1 Peter 1:6,7
