In Pastor Tim Keller’s The Reason for God, 2008, he quotes one of many former athiests: Christians have a “higher standard” following Jesus, than she thought she had by being a moral person.

“Do not conform yourselves to the standards of this world, but let God transform you inwardly by a complete change of your mind. Then you will be able to know the will of God – what is good and is pleasing to him and is perfect.” Romans 12:2 (Good News Translation w/ Apocrypha GNTA)

Matthew 5:

“Agree with your adversary quickly, while you are on the way with him, lest your adversary deliver you to the judge, the judge hand you over to the officer, and you be thrown into prison.”    Verse 28 (NKJV)

“And if your right hand causes you to sin, cut it off and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.”           Verse 30 (NKJV)
