Nothing is Impossible
"The angel answered [Mary]..., 'For nothing is impossible with God.'" Luke 1:35, 37
Why is it so difficult to live our lives with the mindset that nothing we face is impossible for God to overcome or handle for us? I think it mostly has to do with our pride.
We may believe that God can do all things, but we want a crack at it first. Or maybe it's that we believe we've accomplished all that we have without God's help so why do we need Him now?
Pride is an obstacle. I believe it is honestly what keeps us all from growing stronger in our faith in Christ. Pride, which is often accompanied by arrogance, convinces us that our success is 100% up to us, our brute strength, and our tremendous will.
