1 Παρακαλῶ οὖν ὑμᾶς, ἀδελφοί, διὰ τῶν οἰκτιρμῶν τοῦ θεοῦ παραστῆσαι τὰ σώματα ὑμῶν θυσίαν ζῶσαν ἁγίαν εὐάρεστον τῷ θεῷ, τὴν λογικὴν λατρείαν ὑμῶν· 2 καὶ μὴ συσχηματίζεσθε τῷ αἰῶνι τούτῳ, ἀλλὰ μεταμορφοῦσθε τῇ ἀνακαινώσει τοῦ νοὸς εἰς τὸ δοκιμάζειν ὑμᾶς τί τὸ θέλημα τοῦ θεοῦ, τὸ ἀγαθὸν καὶ εὐάρεστον καὶ τέλειον. Rom. 12:1–2, NA28
1 Therefore, I urge you brothers through the compassions of God to present your bodies as living, holy sacrifices, well pleasing to God, which is your spiritual service. 2 And do not be conformed to this age, but be transformed by the renewing of your mind that you may discern the will of God, that which is good and well pleasing and perfect. Rom. 12:1–2, translated from the NA28 Greek text
Deception is our enemy’s most powerful weapon. When a person is deceived into believing a lie they are not intending to participate in something that is wrong. No, they believe they have the truth and all those who oppose what they believe are just wrong. When the lie leads people to believe that their form of ‘religion’ is true Christianity, regardless of how unbiblical it is, they are not actually intending to be evil following an evil system. They are ‘sure’ they have the truth. They are sincere. I am sure the priests of Baal whom Elijah defeated at Mount Carmel were sincere as well.
