'Furtherance' in the Bible

For we have no power against the truth, but only for the furtherance of the truth;

for your fellowship in furtherance of the gospel from the first day until now;

But I would ye should understand, brethren, that the things which happened unto me have fallen out rather unto the furtherance of the gospel;

What then [does it matter]? So long as in every way, whether in pretense [for self-promotion] or in all honesty [to spread the truth], Christ is being preached; and in this I rejoice.Yes, and I will rejoice [later as well],

And having this confidence, I know that I shall abide and continue with you all for your furtherance and joy of faith;

But you know of his proven worth, that he served with me in the furtherance of the gospel like a child serving his father.
