G1414–δυνατέω–dunateō

Who are you that you should find fault with the servant of another? Whether he stands or falls is a matter which concerns his own master. But stand he will; for the Master can give him power to stand.

δυνατεῖ dunatei “able is”

And God is able to bestow every blessing on you in abundance, so that richly enjoying all sufficiency at all times, you may have ample means for all good works.

Δυνατεῖ Dunatei “is able”

since you want a practical proof of the fact that Christ speaks by my lips--He who is not feeble towards you, but powerful among you.

δυνατεῖ dunatei “He is powerful”
