Grieving the Spirit is no small thing but has to do with anger, bitterness and unforgivness;
There seems to be a lot of misunderstanding concerning "grieving the Spirit".
29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice:
32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
You are connecting "grieving the Spirit" with the next part, putting away bitterness and malice and wrath.
The conjoining words show it is actually connected to the previous thought.
This forms a couplet:
31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice:
32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
Vs. 31, don't do these, Vs. 32 do these.
These likewise have a flow of thought:
29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
Don't say corrupt things, only say those things that build up, so that you are giving other grace, and don't make God's Holy Spirit saddened, whereby you are sealed unto the day of redemption.
Give grace through your words. The Holy Spirit is our seal of ownership, and you will make God sad if in your words you take that confidence from others.
Grieve not the holy Spirit of God,
whereby you are sealed unto the day of redemption. This is a statement of ownership, and this seal is there until our day of redemption. Saying otherwise tears down. We are to not do that.
Much love!
