Paul claims he was not disobedient to the heavenly vision (Acts 26:19).
Not to be disobedient is to be deliberately obedient; intentionally faithful; God-wardly focused. Paul clearly could have been disobedient, and that’s the point. Other things could have crowded in, worthwhile things, ministry and Gospel things even, but he had to be obedient to (not his) but the heavenly vision, a heavenly vision given by Heaven’s King.
I randomly opened a page and read this:
“If we lose the vision, we alone are responsible, and the way we lose the vision is spiritual leakage…”
He continues along these lines and then writes,
“Though it tarry, wait for it….We get so practical that we forget the vision. At the beginning we saw the vision but did not wait for it; we rushed off into practical work, and when the vision was fulfilled, we did not see it. Waiting for the vision that tarries is the test of our loyalty to God. It is at the peril of our soul’s welfare that we get caught up in practical work and miss the fulfilment of the vision.”
An objection might be raised here about the necessity of doing “practical work,” but without careful, biblical infused thought, the point would be missed. God’s vision is not anti-practical work per se, but He is against us when we lack the spiritual fortitude of being in Christ and enjoying salvation’s benefits and goals by attending to matters that we find “practical”, Forsyth’s “the sin of bustle.” This is a heretical bastardisation of the Christian faith, and a chief enemy of the believer.
