In everything give thanks: for this is the will of God in Christ Jesus concerning you.
Allow me to give words of encouragement because we are living in some dark, troubling days in our country; be mindful of the words spoken in the Psalm; crying endures for a night; joy comes in the morning (Psalm 30:5 KJV).
If the question was raised, why should I be joyful when there is so much trouble in my life and the world? We rejoice because God, through His internal alarm clock, woke us up this morning and each morning that we are alive; that is praiseworthy. Each day is a new day to tell God thank You even during pain and suffering, tears, and stressful situations; we must say God thank You.
We rejoice because we have a God who cares deeply for each of us and asks that we cast all of our cares upon Him and He will take care of them (1 Peter 5:7 KJV). The God we serve keeps His promises; this is no different.
We rejoice because we have a God who is in the storm with us; reflect on Psalm 23:4 that states, Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me. If the above verses don't give us the comforts to thank God then read Psalm 27:1-4KJV, and then ask why am I fearful and or ungrateful? God is worthy of all praises, glory, and honor. We honor God with our thankfulness.
We thank God for His love, grace, and mercy; thank God.
