for God's glory...

most Christians believe that they can and should do things 'for the glory of God'. giving God more glory, then, becomes the motivation for all types of service.  [1 Cor 10:31 seems to say this.]

i would put a couple different ideas in your head.

first, what is more glorifying to God:

1. the small things we can do for God? or the big things God has done?
2. the small love we express for God?  the gigantic love God expresses for us?
3. the things we do for God?  taking away our sins on the cross?

in every case, i will argue that God Himself gives Himself more glory; you are not as important for giving God glory as you think.

i would propose to you that the most God-glorifying thing that exists is God's love, not your love.  God's love within the Trinity, God's love for us, God's love placed inside of us to love Him and others is, simply, the most glorifying thing that exists.  now, of all of God's great love, the single greatest expression of that love is the gospel; seeing the gospel in truth, believing the gospel in faith, repeating the gospel over and over is, in my opinion, the best way for God's love and God's glory to be expressed.

relax a little bit.  people get really strung-out about doing things for 'the glory of God'; i would propose to you that the main thing about the 'the glory of God' as 'gospel', is to simply believe the gospel and continuously revel in it.

second, what is this thing we call 'the glory of God'???  what is it, really???  is it some glow that surrounds God at all times?  what is it?

i propose that when the bible refers to 'the glory of God', it is referring to the gospel;  'the glory of God' is the gospel.  1 Cor 10:31 is a prime example of this; Paul is exhorting strong Christians to avoid a 'bad witness' before unbelievers.  (unbelievers do not understand freedom in Christ; they generally hold Christians to a high standard and judge the Christians, Christianity and the 'Christian' God by that standard.)  when Paul uses the 'glory of God' phrase, what Paul means is the gospel; Paul could have written, 'do all for the GOSPEL', just as easily.

i know this is hard to believe at first; i encourage you to go through the entire books of 1 Cor, 2 Cor and the other Pauline epistles to see (1) how often 'gospel' and 'glory' are directly connected and (2) see if you can't substitute 'gospel' when you see 'glory'.  when you see this connection, you will relax a little bit.

alternatively, i will propose that the 'glory of God' are His People.  this verse has always stuck with me for this very reason:
Proverbs 14:28  In a multitude of people is a king's glory, But in the dearth of people is a prince's ruin.

Takeaway

the gospel bringing many children to God is the glory of God.  believing the gospel and continuously reveling in it is more important than all the things you think you should do.

Application

it is suitable to simply believe the gospel and continuously revel in it.
