"How do we know if we are grieving the Holy Spirit? What happens if we do? What does the Bible tell us?" from video introduction.
"Given the biblical doctrine of the Trinity, we know that each person of the triune Godhead delights in that which the other persons are doing. There is a mutual indwelling (perichoresis) among the persons of the Godhead — the Father in the Son and the Spirit; the Son in the Father and the Spirit; and the Spirit in the Father and the Son. To put on Christ, then, is to put on the Father and the Spirit as well, and living out the new life in Christ according to the pattern He gives us pleases our triune Creator. On the other hand, violating the standards given to the disciples of Jesus not only grieves the Son of God but also the Father and the Spirit.
The apostle Paul makes this very point in Ephesians 4:30 when he warns us not to “grieve the Holy Spirit of God.” When we sin, the Holy Spirit experiences grief in a manner appropriate to His deity..." from article: Grieving the Holy Spirit
