Snowy,
My heart goes out to you hon (((((Snowy)))))
Sometimes we think we have totally given something to God, when we really haven't. Giving something completely over to God is a very, very hard thing to do. Giving it up totally means you don't fret about it anymore. When we have totally and completely given it over to Him, there is a peace that fills us.
It is an easy thing to "say" we have given it to the Lord, but actually doing it, is not so easy to do. Sometimes it is out of habit (harboring, worrying), sometimes it is because it keeps us in our "safe" zone, and even when it isn't really a safe zone, it is a comfort zone. We get so used to hanging on to things, and we may give 75% to him, but we keep that other 25%. We have to give it up completely, 100%.
Fear can also be a huge stumbling block. Even when we think we are trusting in Him, fear hinders us. We can not have fear and faith at the same time. Not even a little bit. They are a contradiction of one another. Fear is absolutely no match for faith. Fear is powerless over faith, but the old buzzard faced crow devil, will use whatever weakness he can find to manifest the tiniest doubt we have into a fear that we sometimes don't even realize is there.
I will have you in my prayers that whatever is burdening you will be completely turned over to the Lord, and that He will fill you with a renewed energy and strength you have never seen before!
Bless you sister!
