There have been (there still is) days when I have found every reason under the sun to complain and be ungrateful. It is raining, the wind is blowing, the only red light in my town is red, and I could go on and on and on. Being grateful is harder than complaining.
"This is the day which the Lord hath made; we will rejoice and be glad in it." (Psalm 118:24).
After completing my morning devotions, I have been listing 5 or 6 things I am grateful for: the sunshine, friends, sleep, laughter, church services, my health, backpack program for children, praise for good reports, coffee, unexpected notes from friends, etc. Some mornings I may repeat things I have written earlier,but I am okay with that. Learning to count my blessings, boosts my spirit for the day!
There is always something to be grateful for.
