‘And do not grieve the Holy Spirit of God … Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice.’ Ephesians 4.30-31
It is interesting that Paul tells us not to grieve the Holy Spirit, and then goes on to list a range of actions all to do with our relationships with other people. In other words, grieving the Holy Spirit is not so much about our words and actions to him directly, but rather about how he takes offence at our attitude to other people.
Presumably the reverse is also true. If we are seeking to bring pleasure to the Holy Spirit, it is not so much about the praise and worship we offer to him, or whether we have the correct theological understanding of his relationship with the Father and the Son, but rather about how we are treating those around us. If bitterness and rage grieve the Holy Spirit, then forgiveness and love must bring him pleasure.
The good news is that this very day you will have many, many opportunities to bring pleasure to the Holy Spirit. If you fail, or simply forget, there will be plenty more chances! It is not arrogant or boastful to sit in his presence at the end of the day, or the next day, and ask him to bring to your mind those occasions when you gave him pleasure.
