The problem with a lot of Christians is not that they don’t have the Spirit it’s that the Spirit doesn’t have them. The instruction Paul gives to Christians in Ephesians 5v18 is ‘be filled with the Spirit’. It is a passive command in the present tense meaning, it is a continuous action. You don’t get filled today and expect it to cover you tomorrow, just like you won’t eat Sunday dinner later and expect it to carry you over to next Sunday. [Why do we need to be continually filled? Because we leak!] Being filled with the Spirit is a dynamic and ongoing experience – it’s what talking to God, reading your Bible, fellowship and prayer is all about.
