'Offering' in the Bible

Offering the word of life; so that I may have glory in you in the day of Christ, because my running was not for nothing and my work was not without effect.

And even if I am offered like a drink offering, giving myself for the cause and work of your faith, I am glad and have joy with you all:

Not that I am looking for an offering, but for fruit which may be put to your credit.

I have all things and more than enough: I am made full, having had from Epaphroditus the things which came from you, a perfume of a sweet smell, an offering well pleasing to God.
