Those who condemn the self-righteous for the sake of self-discovery do so with ironic self-righteousness.
Timothy KellerFaith in the gospel restructures our motivations, our self-understanding, our identity, and our view of the world. Behavioral compliance to rules without heart-change will be superficial and fleetingโฆ We can only change permanently as we take the gospel more deeply into our understanding and into our hearts. We must feed on the gospel, as it were, digesting it and making it part of ourselves. That is how we grow.
Timothy KellerImportant reminder: It's not fair of you to demand more proof of Christians for their beliefs than you demand for your own.
Timothy KellerA genuinely persuasive argument does not merely tell you that you are wrong about everything. It doesn't just beat on you from the outside. It comes inside your belief system, as it were, and affirms something you believe strongly. And then it says - well if you believe this (A) then why in the world can't you see that B is true?
Timothy KellerAn idol is something that we look to for things that only God can give. Idolatry functions widely inside religious communities when doctrinal truth is elevated to the position of a false god. This occurs when people rely on the rightness of their doctrine for their standing with God rather than on God himself and his grace. It is a subtly but deadly mistake. The sign that you have slipped into this form of self-justification is that you become what the book of Proverbs calls a 'scoffer'.
Timothy KellerChristians tend to motivate others with guilt. We tend to say: You would do this if you were really committed Christians, indicating that we are committed and all that is needed is for others to become as good as we are! This is why so many churches quench the motivation of people for ministry. In our shoes, Paul would say: Remember the grace God has showered on youโwhat does living out and enjoying that grace look like in this situation?
