Christianity is a lot like that. It is like a walk up a down escalator. If you try at all you can go up faster than it is taking you back down, but stop and you're in the basement. You can't stop. You have to keep moving.
Today is the day of salvation.
Jesus spoke of us wearing a yoke with Him. A yoke, believe it or not, was what was used to tie two animals together to pull a plow. He said He would be our yokefellow and help us pull the plow. Too many people see the yoke and think that looks too much like work and never go even near Him or it. He said come unto me all of you who labor and are heavily burdened and I will give you rest.
