From Spurgeon's sermon, "Spiritual Gleaning"

For many Christians, it is enough for them to be
sound in doctrine, and tolerably correct in practice.

They care far less than they should about having intimate
communion with Jesus, by the power of the Holy Spirit.

It is only in proportion as we hold fellowship with
Christ, and commune with him, that either ordinances,
or doctrines, or promises can profit us.

All other things are dry and barren
unless we are enjoying the love of Christ,
unless we bear his likeness,
unless we dwell continually with him,
and rejoice in his love.
