Cast all your cares, upon the Lord, for he cares for you and only he knows what you are going through, so it is best that you cast your cares upon the Lord.
I can say one thing categorically which is although we have humans with empathy and maybe sympathy as well but none of those attributes of a human can be compared to the love and care God has for us.
Although we have humans who know how to stand in the gap for their friends and loved ones even strangers when they are reached out to but the truth is God doesn't just know how to stand in the gap for us, he knows exactly how we are feeling and feels the pain we are going through.
Cast all your cares upon the Lord because only he can not disappoint us at the time of our needs, Men may disappoint us and frustrate us at the time of our needs, men may fail us, men may be selfish, men may think about themselves first, their needs and what they stand to gain or loss from us but God can not think about that first before deciding to help us.
Cast all your problems upon the lord because he is the best person to do that, he never fails, he never lies, and he never takes advantage of our weaknesses and weakest moments, he makes sure to follow us up from the beginning of the journey or challenges to the end even when we fail to rush to him for help.
Cast all your problems, your challenges, your headaches, and your heartaches. Cast all your fears, your weakness, your addiction, your cravings, and your emotional turmoil upon the Lord, only he knows how best to handle us and calm us when we have a racing heart.
Cast your happy moment, sad moment, worst moment, fun moment, Thanksgiving moment, worship moment, wailing moment, crying moment, laughing moment, and memorable moment, upon the Lord, he knows how best and what's best for us all. So, cast your all and all upon the Lord.
