Now concerning spiritual gifts, brothers and sisters, I do not want you to be uninformed. 2You know that when you were pagans, you were enticed and led astray to idols that could not speak. 3Therefore I want you to understand that no one speaking by the Spirit of God ever says “Let Jesus be cursed!” and no one can say “Jesus is Lord” except by the Holy Spirit. (1 Corinthians 12:1-3, NRSV)
You can not say Jesus is Lord except by the Holy Spirit.
Meaning if you say that, then the Spirit is within you. Does that mean everything we do and say then is what the Spirit wants us to do? If we believe in free will then no. We can always follow our own way.
So I beseech you to follow the Spirit and head the leading of God.
