"We have too frequently been as harmless as doves without being as wise as serpents. This has caused many hungry intellectuals to conslude that there are no answers in evangelical Christianity to the problems which they see…since we know that truth does not change and that God's method of dealing with souls is ever the same, we must be faithful in our wielding the slaying sword of the Spirit.Thus only can we meet their real need. God never raised any soul to life through the Gospel without first slaying him with the law. With honest skeptics, for such often fall into this class, we should be firm and fearless while we speak the truth in love…No man has ever been argued into salvation; no man has ever been led to Christ through human wisdom. Only the presentation of human need and Christ's sufficiency will do it"
