I’m certainly not an English scholar.
Truth be told, I had no idea what an article or a tense really were within language until I had to learn Koine Greek for my Theology Degree.
So, I have no real clue if the present continuum is an actual tense in any language, never mind biblical Greek.
That being said, the idea of the present continuum is essential to the Christian faith.
Why?
Because there’s so many elements that need to be both in the present AND in the continual.
Believe.
Repent.
Forgiveness.
Sanctification.
Being filled by the Holy Spirit.
All of these are things which occur at a moment in time.
But, they are also things which need to continue happening both now and into the future.
You had an initial moment of belief. But you must continue to believe.
You had an initial moment of repentance. But you must continue to repent.
You had an initial moment of forgiveness. But you must continue to forgive and be forgiven.
You had an initial moment when sanctification began. But you must continue to be sanctified.
You had an initial moment of the Holy Spirit filling you. But you must continue to be filled.
The Christian life is a journey within the present continuum.
