Step 2:Man
Man is a sinner:

For all have sinned and come short of the glory of God;
Romans 3:23

He cannot save himself:

Be ye therefore perfect, even as your Father which is in heaven is perfect.
Matthew 5:48

Imagine you were at an old fashioned ice cream pallor. One you haven’t been to for a long time. You are sitting at the counter so you can watch your shake as it is being made. You order your favorite flavor and watch as patiently as possible. Just as all of the ingredients are put into the cup for blending, the person making it sneezes! RIGHT INTO YOUR MILK SHAKE! The person wipes their nose with their hand and finishes up your shake and brings it to you as if nothing happened.  Are you going to want that shake now?  Of course not! Your perfect milk shake now has been contaminated with someone else’s germs! Just as that shake is not acceptable to us, we are not acceptable to a Perfect God with just one sin in our life.
