When you have doubts or fears open these scriptures to God's word and He will open your eyes to the truth.
But Jesus beheld them, and said unto them, With men this is impossible;
but with God all things are possible.
Jesus beheld them- to look on, to observe, to discern clearly
He wanted them to look directly at Him.
As a parent I do that with my children
you look at me when I am talking to you.
And Jesus looking upon them saith, With men it is impossible, but
not with God: for with God all things are possible.
