At the cross, we see the worst that sin can do, as humanity - of which each one of us is a part - crucified the Lord. But at the cross, we also see that the most that sin can do cannot thwart God's salvation.
Timothy KellerThe doctrine of grace and redemption keeps us from seeing any person or situation as hopeless.
Timothy KellerWhile the difference between a bad sermon and a good sermon is mainly the responsibility of the preacher, the difference between good preaching and great preaching lies mainly in the work of the Holy Spirit. . . . We should do the work it takes to make our communication good and leave it up to God how and how often he makes it great for the listener.
