What motivates you to give thanks to God?
In times like this, people often give thanks to God as some sort of appeasement to God to satiate their fears. Like some sort of sacrifice meant to initiate a sense of peace and put reason on an otherwise unreasonable event. We can also submit praise as an exalted form of humility. Like saying to ourselves, “I'll praise Him even though He doesn’t deserve any praise.”
Here is the problem, our thinking praise must have a reason. But scripture says...
1Th 5:18 In every thing give thanks: for this is the will of God in Christ Jesus concerning you.
If we are to praise Him in every thing then there is no one event that can initiate praise. Because of this, praise becomes a celebration that God is in control and we get to exalt Him in the face of all joy and every sorrow alike.
I do not know what your day brings, but I know the ONE who authors it and every event leading to it and every outcome from it. I praise Him because there is none else to praise, rely on and trust in every situation.
Praise is in fact just calling God, GOD.
