May I commend the article 'Time and Eternity' in the New Dictionary
ofTheology (IVP, both USA and UK) Dr J E Colwell notes with Garry that;
'The conception of eternity as timelessness was the eventual outcome of the
attempt to express Christian truth within the framework of Greek
metaphysics.'
Colwell is of the view that:
'The living God is not non-temporal, but is revealed as active in the flow
of man's time. The temporal distinction between God and man is that he is
enduring and changeless in time; God possesses lasting time in contrast to
man's fleeting and passing time (Ps90:1ff).'
