As my first answer on this site I would like to agree with Nhi in that heaven is where there is union between God and man. How does this occur?
Mat 23:37 O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!
The new Jerusalem is the heavenly place of union with God. Christ dwells in our hearts by faith. This is the process of the spirit of God given by the father in Ephesians 3. Notice the work of the father, and the work of the spirit that Christ may dwell in your heart by faith. One of the fruits of the spirit is faith. The greek word pistis for faith is a fruit in us given freely as a gift so that the full character of Christ shown in the fruit of the spirit would be formed in us.
(Eph 3:14) For this cause I bow my knees unto the Father of our Lord Jesus Christ,
(Eph 3:15) Of whom the whole family in heaven and earth is named,
(Eph 3:16) That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;
(Eph 3:17) That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love,
Reading on from these verses above leads us to further verses on love (for God is love). These verses state that love leads to the fulness of God. Abiding in God has much to do with abiding in love. When we choose to love the God way His spirit helps us. You cant give away what you have not received. So the command to BE FILLED with the spirit is to allow (surrender or yield) to the spirits prompting to love God and to love people. If you abide in the lord then you WILL walk as he walked.
1Jn 2:6 He that saith he abideth in him ought himself also so to walk, even as he walked.
Singing and being thankful is also part of this process of being filled with the spirit.
Eph 5:18 And be not drunk with wine, wherein is excess; but be filled with the Spirit;
Eph 5:19 Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord;
Eph 5:20 Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ;
How can you read the above verses and not connect melody in your heart to the Lord with being filled with the spirit? Some might argue that it does not but I would differ. It goes along with many commands to "rejoice always". Rejoicing is a decision that God is at work and that he has heard our prayer that is prayed in faith according to the will of God.
1Jn 5:14 And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:
1Jn 5:15 And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
That confidence is a joyful expectation that He is at work and that our prayer has been answered. Mark 11:24 backs this up wonderfully.
Relying and depending on the spirit of God for every word and action is abiding in Christ. Christ means the anointed one. Allowing Him to fill you up with love is to allow Gods action in your life. Jesus said that his words were spirit and life. He also said
Joh 15:7 If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
Abiding in Him means abiding in HIS living word. Mary said "be it unto me according to thy word" and Christ was formed in her. In the same manner spiritually Christ can be formed in us. The peace of God (the prince of peace himself) will guard and hearts and minds in Christ if we give our anxieties to Him Phil 4. The joy of the Lord (fruit of the spirit) is our strength.
Knowing that he lives in us (IN CHRIST) has an action every moment of the day.
(Act 17:28) For in him we live, and move, and have our being;
The first part of that is to love God and receive His love (walk in the Spirit) The next part is to do this and love others in HIM. To walk in Christ is to walk in light.
(Mat 5:14) Ye are the light of the world. A city that is set on an hill cannot be hid.
How do we do this?
(1Jn 2:9) He that saith he is in the light, and hateth his brother, is in darkness even until now.
(1Jn 2:10) He that loveth his brother abideth in the light, and there is none occasion of stumbling in him.
(1Jn 2:11) But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.
putting this altogether an adding a bit more
- Let God love you
- Walk in Him (walk in love for God is love)
- Choose to love others
- Be filled with the spirit - singing and being thankful and a whole lot more
- meditating on the Word of God - man shall not live by bread alone but ....
- See and hear Christ in His body. 1 Cor 12
- Pray without ceasing - stay connected by faith
- Let Christ live in your heart by faith - like a child dpends totally on its parents. For of such is the Kingdom of God
