30And do not grieve the Holy Spirit of God [but seek to please Him], by whom you were sealed and marked [branded as God’s own] for the day of redemption [the final deliverance from the consequences of sin]. [Eph 1:13, 14; Phil 3:20, 21]
30Do not make God’s Holy Spirit mourn. The Holy Spirit is the proof that you belong to God. And the Spirit is the proof that God will set you completely free.
