The Lord is our refuge and our strength. When one calls on the Lord, He always answers. We just don't like His answer. There is always a reason God says 'no'. God always has something better for our future. ~Me
When GOD says do not fear, that means GOD is the one who will back you up and support you or come in and help you! So the truth is you have to make absolutely sure it is GOD and not you otherwise you are not going to get the back up of GOD.
I will not abandon My Own Inheritance. For I have drawn you My children with loving kindness. Do not worry for your life. Cease all striving and strife. I have called you My own special possession. Live free in Christ and tell others about Him.
