By nature, we only have sin and darkness within us, the Bible says so. You see, the Gospel is about what is within you, not what you wear, or where you attend church. In order for God, Christ Jesus, and the Holy Spirit to be living within someone, that person must by a deliberate, personal act of faith simply rely on Christ's Atoning Blood alone; that person must receive Christ Himself spiritually by faith into his heart, soul and body. Fix your faith in the Lamb of God's Blood. Until you have done that, you will remain in your unregenerate natural state with the wrath of God abiding on you, not the love of God. What is within you right now is what matters. Religion cannot help you, only the Holy Spirit can regenerate, and only the Blood of Christ can rescue you from sin's power and penalty. Below is a short Bible study on the Bible phrase "in you". You will see that the Bible has plenty to say about what is within a human being.
And ye have not God's word abiding in you: for whom He hath sent [Christ Jesus], Him ye believe not. But I know you, that ye have not the love of God in you. Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink His blood, ye have no life in you. I know that ye are Abraham's seed; but ye seek to kill Me, because My word hath no place in you. 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. Abide in Me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in Me. If ye abide in Me, and My words abide in you, ye shall ask what ye will, and it shall be done unto you. These things have I spoken unto you, that My joy might remain in you, and that your joy might be full.

But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of His. And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness. But if the Spirit of Him that raised up Jesus from the dead dwell in you, He that raised up Christ from the dead shall also quicken your mortal bodies by His Spirit that dwelleth in you. Even as the testimony of Christ was confirmed in you. Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's. And thus are the secrets of his heart made manifest; and so falling down on his face he will worship God, and report that God is in you of a truth.
So then death worketh in us, but life in you. For behold this selfsame thing, that ye sorrowed after a godly sort, what carefulness it wrought in you, yea, what clearing of yourselves, yea, what indignation, yea, what fear, yea, what vehement desire, yea, what zeal, yea, what revenge! In all things ye have approved yourselves to be clear in this matter. And by their prayer for you, which long after you for the exceeding grace of God in you. Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
My little children, of whom I travail in birth again until Christ be formed in you. One God and Father of all, who is above all, and through all, and in you all. Being confident of this very thing, that He which hath begun a good work in you will perform it until the day of Jesus Christ. Let this mind be in you, which was also in Christ Jesus. For it is God which worketh in you both to will and to do of his good pleasure. Which is come unto you, as it is in all the world; and bringeth forth fruit, as it doth also in you, since the day ye heard of it, and knew the grace of God in truth. To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory. Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe. That the name of our Lord Jesus Christ may be glorified in you, and ye in Him, according to the grace of our God and the Lord Jesus Christ. That the communication of thy faith may become effectual by the acknowledging of every good thing which is in you in Christ Jesus.
Make you perfect in every good work to do His will, working in you that which is wellpleasing in His sight, through Jesus Christ; to Whom be glory for ever and ever. Amen. But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear. And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge; And to knowledge temperance; and to temperance patience; and to patience godliness; And to godliness brotherly kindness; and to brotherly kindness charity. For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.
Again, a new commandment I write unto you, which thing is true in Him and in you: because the darkness is past, and the true light now shineth. I have written unto you, fathers, because ye have known Him that is from the beginning. I have written unto you, young men, because ye are strong, and the word of God abideth in you, and ye have overcome the wicked one. Let that therefore abide in you, which ye have heard from the beginning. If that which ye have heard from the beginning shall remain in you, ye also shall continue in the Son, and in the Father. But the anointing which ye have received of Him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in Him. Ye are of God, little children, and have overcome them: because greater is He that is in you, than he that is in the world.
