And don’t grieve God’s Holy Spirit. (Ephesians 4:30)
A lot of times, people recognize the personality of the Father and the Son. But they don’t often recognize the personality of the Spirit.
But the Holy Spirit is not a mere power like the Force is in Star Wars. He has personality. And he can be grieved.
He grieves when we harden our hearts against him. (18)
He grieves when in our pride we break the unity of his people. He grieves when our words are filled with bitterness, anger, wrath, slander, and malice toward each other instead of grace. (29, 31)
Let us not grieve the Spirit. Instead, let us always keep humble, softened hearts toward him and toward his people.
