'Unless' in the Bible

“For I say to you that unless your righteousness (uprightness, moral essence) is more than that of the scribes and Pharisees, you will never enter the kingdom of heaven.

and said, “I assure you and most solemnly say to you, unless you repent [that is, change your inner self—your old way of thinking, live changed lives] and become like children [trusting, humble, and forgiving], you will never enter the kingdom of heaven.

He went away a second time and prayed, saying, “My Father, if this cannot pass away unless I drink it, Your will be done.”
