John Stott from his Commentary on Ephesians.
When Paul says to us, ‘Be filled with the Spirit’, he uses a present imperative implying that we are to go on being filled. For the fulness of the Spirit is not a once-for-all experience which we can never lose, but a privilege to be renewed continuously by continuous believing and obedient appropriation….
To the defeated Paul would say, ‘Be filled with the Spirit, and he will give you a new love, joy, peace, patience, kindness, goodness, faithfulness, meekness and self-control.’ To the complacent Paul would say ‘go on being filled with the Spirit. Thank God for what he has given you thus far. But do not say you have arrived. For there is more, much more, yet to come.’
