Actually as Christians we have to learn to be completely reliant on God, because of our existence this is not easy to do but with God's support and only a little faith we can.
If in all areas of our lives we depend on God, we continue to face the adversities and increase the degree of our confidence on the way, I clarify a bit:
My family and I have encountered numerous situations under which God has instructed us that He will always be the answer to all and that if we wait for God we will never be disappointed or frustrated, we have gone through difficult times with our little girl who has seen very vulnerable health on many occasions, as humans we can tell it is not pleasant.
At first we were frustrated and seemed to lose hope on the way, I can not honestly deny that if we feel a little scared but not a scaredness that makes us doubt that God is for us, that God is fighting for us.
I believe that my daughter is of God, made by God to worship Him, and I know that God cares for His children, we as a father bring up God's child, and He looks over her, with each day I have this written in my heart and I believe that god loves us, God is a physician extraordinaire and the owner of my entire life.
Do not stop putting your trust in God, for he cares for you
