Have you ever felt like giving up? Like maybe nothing was going your way so you should just throw in the towel? I have and those are usually the times when I am trying to do things in my own strength. It never ceases to amaze me when I look back at where I've come from. It is simply amazing that Jesus Christ chose to die for sinners like you and I.
Now, faith is the substance of things hoped for, the evidence of things unseen. Hebrews 11:1
