'Grow' in the Bible

I planted, Apollos watered, but God [all the while] was causing the growth.

So neither is the one who plants nor the one who waters anything, but [only] God who causes the growth.

Now about food sacrificed to idols, we know that we all have knowledge [concerning this]. Knowledge [alone] makes [people self-righteously] arrogant, but love [that unselfishly seeks the best for others] builds up and encourages others to grow [in wisdom].

Be on guard; stand firm in your faith [in God, respecting His precepts and keeping your doctrine sound]. Act like [mature] men and be courageous; be strong.
