'Certainly' in the Bible

But if, while we sought to be justified in Christ, we ourselves also were found sinners, is Christ a servant of sin? Certainly not!

Certainly all who depend on the actions of the Law are under a curse. For it is written, "A curse on everyone who does not obey everything that is written in the Book of the Law!"

Is the law therefore contrary to God’s promises? Absolutely not! For if a law had been given that was able to give life, then righteousness would certainly be by the law.

But I say, walk habitually in the [Holy] Spirit [seek Him and be responsive to His guidance], and then you will certainly not carry out the desire of the sinful nature [which responds impulsively without regard for God and His precepts].
