"...Be filled with the Spirit" (Ephesians 5:18)
When we think of the Person of the Holy Spirit, we should think of Him as gracious, loving, kind, and gentle - just like our Lord Jesus Christ Himself!
When the Scripture says, "Grieve not the Holy Spirit of God," it is telling us that He loves us so much that when we insult Him, He is grieved; when we ignore Him, He is grieved; when we resist Him, He is grieved; and when we doubt Him, He is grieved.
Thankfully, we can please Him by obeying and believing. When we please Him, He responds to us just like a pleased father or loving mother responds. He responds to us because He loves us!
Think of the tragedy and the woe of this hour - that we neglect the most important One who could possible be in our midst! He is the Holy Spirit of God - yet many are guilty of ignoring and neglecting Him!
Let me assure you that this is the most important thing in the world - that this blessed Holy Spirit is waiting now and can be present with you this minute. Jesus, in His body, is at the right hand of God the Father Almighty, interceding for us. He will be there until He comes again.
But He said He would send another Comforter, the Holy Spirit, His Spirit. We cannot be all that we ought to be for God if we do not believe the Comforter, the Holy Spirit has been sent to be to us all that Jesus would be if He were here now!
