What do you think of Isaac Watts as a dispensationalist?
The link to the article cited is here.
Thanks A-M for linking to it. Pity there were only a few replies.
It does indicate that dispensation is a commonly used term. He quotes Ryrie -
I think the association of time with dispensation is due to the way Eph. 1:10 reads - the dispensation of the fulness of time implying other dispensations relating to other times.
Perhaps Ephesians 1 doesn’t present as you desire
Ephesians 1:
7In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace 8which He lavished on us. In all wisdom and insight 9He made known to us the mystery of His will, according to His kind intention which He purposed in Him 10with a view to an administration suitable to the fullness of the times, that is, the summing up of all things in Christ, things in the heavens and things on the earth. In Him 11also we have obtained an inheritance, having been predestined according to His purpose who works all things after the counsel of His will, 12to the end that we who were the first to hope in Christ would be to the praise of His glory. 13In Him, you also, after listening to the message of truth, the gospel of your salvation—having also believed, you were sealed in Him with the Holy Spirit of promise, 14who is given as a pledge of our inheritance, with a view to the redemption of God’s own possession, to the praise of His glory.
See how the emphasis is upon the administration and that administration was suitable to (fit the circumstances of) the times (age)?
The basic thread of this passage is both the presentation of the gospel and the hope in the promise. That which is not time related but that commission, that stewardship, in which believers are to present.
