We begin this sermon considering that Christianity is no add on in the believer’s life. God is not merely useful to us but absolutely necessary. God does not just come to upgrade our lives – to make them better. But rather he must become the centre of our lives as we deny ourselves taking up our cross and following Jesus.
In Romans 8, Paul makes it plain that we cannot have any halfway ground with Jesus. He is either our all in all, or he is not. We are either in Christ or we are not, united to him or not. We are either condemned or we are not. Those who are truly united to Christ also have the Spirit. Those who are not united to him do not have the Spirit and therefore cannot please God.
Some people therefore have the Spirit, Some people do not have the Spirit. But for those who do have the Spirit – the real question must be Does the Spirit have you?
