John Piper, On What It Means to Delight in God

“Delight in the glory of God includes, for example, hatred for sin, fear of displeasing God, hope in the promises of God, contentment in the fellowship of God, desire for the final revelation of the Son of God, exultation in the redemption he accomplished, grief and contrition for failures of love, gratitude for undeserved benefits, seal for the purposes of God, and hunger for righteousness. Our duty toward God is that all our affections respond properly in his reality and so reflect his glory.” (The Supremacy of God in Preaching, pg. 78)
