You still haven't show us how "Let the word of Christ dwell in you richly" (Col 3:16) means waiting in silence until we feel God speaking in us as you originally asserted.
Lets look at Colossians 3:15 and 16 again
"15 And let the peace of God rule in your hearts, to the which also ye are called in one body; and be ye thankful."
Here we see that believers are to "let" the "peace of God" rule ( or govern) in their hearts. This inward ruling and governing is where the rule of faith and practice begins. Here again is the primary rule. If men come together as "one body" in assemblies and they do not have Gods peace ruling in their hearts they are then in a restless spirit or the flesh and sin. Even when they eat the Lords supper they must examine themselves and search their hearts and confess any sin. How can any come to a true order where God is leading and giving gifts and revelation and speaking immediately through prophets and leading teachers and other gifts if they are not at peace with God in their hearts. If they have a clean conscience and a conscience void of offense they can then function in Gods order, or rule and governing in their hearts.
They are to "let" the peace of God rule. This implies seeking the Lord not their own way. To live and move in the power and character and authority of Jesus Christ.
We read another verse about the peace of God that seems to keep coming up in Hebrews 13;20,21
"20 Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant, 21 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."(Hebrews 13:20,21 KJV)
Notice that the God of peace" makes them perfect in every good work. These good works would be all the work of faith they do, and all the ministry, teaching and admonishing, and in psalms and hymns and spiritual songs and in prophesying and exhorting etc. This is the only way they can do so. if they are in the peace of God and let the peace of God rule in their heart.
Romans 15:33
Now the
God of peace be with you all. Amen.
The opposite of letting the peace of God rule in their hearts is to be in anxiety and worry and fear before God. This could be because of sin or double mindedness, carnality or lack of love etc.
Peace implies silence in his words and believers coming before God in silence and waiting on the Lord for all good things. The busy stress of a carnal mind , is not in the peace of God, nor is the anxiety of a man in sin and a evil heart. If any are in sin or anxiety and worry how can they let the peace of God “rule” or govern and direct them inwardly? How can they know God or have their faith work by love where God dwells in them to lead, if they are not listening and resting in Christ in their hearts.
Psalm 46:10
"Be still, and know that I am God:"
they also are to examine themselves in silence in the meetings as we read
1 Corinthians 11:28
"But let a man examine himself, and so let him eat of that bread, and drink of that cup."
and this self examining can be as we gather in ministry and all things as well, for Paul said to the Corinthians
2 Corinthians 13:5
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?
"16 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."(Colossians 3:16)
Then, after they have examined themselves and come to let Gods peace rule in their heart to dispell the darkness and busy restlessness of their carnal minds can they hope to have any edification for themself or others in Christ . They also will need confession and self examination in this process at times. . Then, when they “let” the peace of God “rule” in thier hearts, they are to be called together in one body. This refers to the assembly of the saints and the way all are to walk in God's order here. Then they can "let the word of Christ dwell in them richly" and from Christ Jesus working in them all effectually they can teach and admonish eachother and in psalms and hymns and spiritual song. This is all
as Christ the head works in them all. Paul touched on their completeness in Christ as the head in the previous chapter where he says they are
complete in him which is the head and he warns them of being drawn away by men and vanity and traditions of men and rudiments of the world. He warns them to
"beware" of anything that is not after Christ. He also speaks of the entire body edifying eachother as he did in
Ephesiasn 4;15,16. There we see clearly that Jesus Christ works in all to effectual make increase of the body to the edifying of itself in love.
This inward work in the body is not as men rush ahead in their own ways but as they are led BY God and in His peace where the word of Christ dwells in them. Where Jesus Christ is in believers he speaks His word as well. Yes the word can be heard in our spirit and as we also hear from scripture. But the inward work is of God working in us. Paul said they put on the new man where Christ is all and in all.
Paul said similar words to the Ephesians in Acts 20 when he commended them to God and to the word of His grace that is able to build them up. Paul says in Colossians 3:16 that the word of Christ is connected to the grace in the heart. Gods grace works in us as well. Paul uses the words "with grace" connected to God ruling in the heart and the Wird of Christ dwelling in them.
Colossians 3:16. 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.”
We know that all true worship is also
BY Jesus Christ in us and not of ourself, we read this here
Hebrews 13:15
By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of our lips giving thanks to his name.
Hebrews 2:11,12
"11 For both he that sanctifieth and they who are sanctified are all of one: for which cause he is not ashamed to call them brethren, Saying, I will declare thy name unto my brethren, in the midst of the church will I sing praise unto thee.”
John 4 - 23. But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.”
"17 And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him."
Then Paul says this in verse 17, to do all in the
"name of Jesus Christ", all includes what we do in word and in deed.
This expression "in the name of Jesus Christ" does not mean to literally say the words
"in the name of Jesus Christ" after every word and action. But it means to do all in the character, authority , power, life and leading of Jesus Christ who works in all believers. Jesus said without him they can do nothing.
So clearly Paul is not leading them to speak, or act or minister as the carnal fleshly wisdom of men or excellency of speech with their craftiness and human skills or their man made programs and forms without power. No he warns them of men who would beguile them and deceive them,he said
"4 And this I say, lest any man should beguile you with enticing words. 5 For though I be absent in the flesh, yet am I with you in the spirit, joying and beholding your order, and the stedfastness of your faith in Christ. 6 As ye have therefore received Christ Jesus the Lord, so walk ye in him: 7 Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving. 8 Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. 9 For in him dwelleth all the fulness of the Godhead bodily. 10 And ye are complete in him, which is the head of all principality and power:"(Colossians 2:4-9 KJV)
Paul says we are to pray without ceasing. This constant state of communion with God and being led of the Spirit is a daily walk. We are to bring every thought to the captivity of Christ, every thought.
