John 14:12-18 says, "Verily, verily, I say unto you, He that believeth on Me, the works that I do shall he do also; and greater works than these shall he do; because I go unto My Father. And whatsoever ye shall ask in My name, that will I do, that the Father may be glorified in the Son. If ye shall ask any thing in My name, I will do it. If ye love Me, keep My commandments. And I will pray the Father, and He shall give you another Comforter, that He may abide with you for ever; Even the Spirit of truth; whom the world cannot receive, because it seeth Him not, neither knoweth Him: but ye know Him; for He dwelleth with you, and shall be in you. I will not leave you comfortless: I will come to you".
 
John 14:21-24 says, "He that hath My commandments, and keepeth them, he it is that loveth Me: and he that loveth Me shall be loved of My Father, and I will love him, and will manifest Myself to him. Judas saith unto him, not Iscariot, Lord, how is it that Thou wilt manifest Thyself unto us, and not unto the world? Jesus answered and said unto him, If a man love Me, he will keep My words: and My Father will love him, and We will come unto him, and make Our abode with him. He that loveth Me not keepeth not My sayings: and the word which ye hear is not Mine, but the Father's which sent Me".

The Holy Ghost comes to live within you when you repent of your sins and make Jesus Christ your Lord and Savior. As you yield yourself to the Holy Ghost within you, you are enabled by Him to obey the commands of the Lord written in His Word. When you ask God the Father to baptize you with the Holy Ghost and fire, the Holy Ghost comes upon you giving you the power, or dynamic ability of the Lord, to be a witness for Him to others. Amen.
