You cannot confess that Jesus is your Lord unless the Holy Spirit is in you.
In order to do that, He must actually be your Lord.
Jesus said,
Luk 6:46, And why call ye me, Lord, Lord, and do not the things which I say?
If Jesus is not really your Lord, then to say with your mouth "Jesus is Lord" is not a confession. A confession is to agree with God, and if it is not the truth, then God is not saying it; and therefore to mouth the words is not to agree with Him.
To say “ Jesus is Lord” is to say that Jesus is God in the Flesh.....as Peter said,” You are the Christ...the Son Of The Living God”...... that was apparently all that Jesus needed to hear......Jesus took that confession and made it the Rock that He built His church upon.....
......you insist on hearing more.... Peter did NOT say to Jesus, “ I now make you Lord of my Life” and
Jesus ran with that, declaring “that” as the Rock upon which He would build His Church.....
Peter confessed that Jesus was who He Said He was —- he was a Believer.We need to do the same ....Do you Believe Jesus was who He said was —- “ The Resurrected Lord that died for you Sins?” If you Believe that, you Believe the Gospel .....Paul said if you Believed the Gospel—- Plus Nothing—- you are Saved . End of Story.
