Charles H. Spurgeon on Psalms 43:4

Unto God. Believers are not satisfied in the use of religious duties, unless they arrive at God himself in those duties. We speak not here of that arrival at God himself which is by and after all duties, to a beatific vision of God in glory, but we speak of that arrival at God himself which is to be had in duties, while we are in the exercise of duties; namely, to attain to God's special presence in them, in an actual communion, communication and conversing with God, so that we are spiritually sensible he is with us therein. I say God's special presence and actual communion, to distinguish it from that ordinary habitual presence and communion of God's being with a believer at all times. Joh 14:16. Nathanael Homes.
