If we say, 'I believe in Jesus,' but it doesn't affect the way we live, the answer is not that now we need to add hard work to our faith so much as that we haven't truly understood or believed in Jesus at all.
Timothy KellerIf you're avoiding sin and living morally so that God will have to bless you and save you, then you may be looking to Jesus as a teacher, model, and helper, but ironically you are avoiding him as Savior. You are trusting in your own goodness rather than in Jesus for your standing with God.
Timothy Keller
