Jesus cracked the code to getting rid of overwhelm.
In Matthew 6:34, He taught us something that few follow because it is tough to lay down human wisdom to embrace what He is revealing.
Overwhelm only comes when we get our thoughts caught up in the future instead of today.
Let's say you have some bills coming due. It only becomes overwhelming when you worry about whether you will have enough by the time it comes due.
As soon as we venture into tomorrow's provision, we've entered the land of ungodly thinking. Such thinking produces worry, robs you of faith, and prevents the provision of God from getting to you.
We can only receive from God by faith. Faith is the absence of worry. So, if you allow worrisome thoughts to continue, you've just stepped out of faith.
You may not have others' permission, but according to Jesus, you have not only God's permission, but His command not to concern yourself with tomorrow.
This is the pinnacle of a life marked by absolute trust in God.
