1 Corinthians 14:5

14:5 I wish you all spoke in tongues, but even more that you would prophesy. The one who prophesies is greater than the one who speaks in tongues, unless he interprets so that the church may be strengthened.

1 Corinthians 15:10

15:10 But by the grace of God I am what I am, and his grace to me has not been in vain. In fact, I worked harder than all of them – yet not I, but the grace of God with me.
