There are many serious misunderstandings about being filled with the Holy Spirit.
There are those who hold a doctrinal position that is correct to a point, but they never experience Him. They believe that when we are born again, He indwells, and of course that is what the Bible teaches, But those who hold to that as a teaching alone don't experience Him. I do not speak of fireworks.
Then of course, there are those who crave a show all the time. Wrong.
There is no question that all who are born again have the Holy Spirit "seal of promise" and He indwells. There is a witness of Sonship that nothing can remove, and absolutely, there is an assurance of salvation.
But oh Soldier of The Cross, there is so much more. I do not speak of supernatural explosions or any kind of geeky show.
He who Indwells is a Person, and He reveals Jesus. He leads and He assures. He prods and He restrains. If the Soldier of The Cross does not know that he or she is experiencing the Holy Spirit of God, something is wrong.
We are called out of this world into another, and we have The Alongside One who enables and guides. He consoles and He chides.
You understand God's Word because The Interpreter lives in you.
No cheapening of the Presence of the Holy Spirit. Learn to be alert. Recognize God.
Pray about this because if you don't, you will miss His Presence.
Soldier, we are to be being filled, all the time. Go after Him. Pursue Him.
Do it in prayer.
Do it in your thought life.
Do it in your speech.
Tell Him how much you want Him. Tell Him you want to be filled. Again and again and again. And then again.
Tell Him aloud and do it now. Don't wait.
