If I wash myself with snow water, and make my hands never so clean; yet shalt thou plunge me in the ditch.
Salvation is not possible through our own doing. No matter how much care we take, no matter how clean we look on the outside, no matter how much Scripture we have memorized, no matter how many times we go to church or Sunday school, salvation cannot be obtained this way. Only by believing and trusting in the Lord Jesus can we gain entrance to heaven. Are you saved?
