I suggest you review ALL the other scriptures that clearly state Jesus’s death alone and faith in Him is ALL that is needed for the sufficiency of his grace.
I don’t disagree with what you have said but there is MORE. Many can say and have said your very words and have not been sufficient. Some have cast out demons in His name yet, Jesus says “go away”.
Your faith is a gift of God, not of your own doing. Jesus dying on the cross is a gift of God and not your doing. Without being baptized in God’s Spirit we are lost. Get over the idea that God’s Spirit is only speaking in tongues.
I repeat, get over the idea that being baptized in the Spirit is ONLY speaking in tongues. I thought the same at one time.
Joh 3:5 Jesus replied, “I assure you, no one can enter the Kingdom of God without being born of water and the Spirit.
Joh 3:6 Humans can reproduce only human life, but the Holy Spirit gives birth to spiritual life.
Joh 3:7 So don’t be surprised when I say, ‘You must be born again.’
Joh 3:8 The wind blows wherever it wants. Just as you can hear the wind but can’t tell where it comes from or where it is going, so you can’t explain how people are born of the Spirit.”
We are told we can’t explain how people are born of the Spirit. It is a mystery, but we can still explore the mystery with God.
Do you have any thoughts on the mystery?
being born of the spirit does not require an immersion in water.
Saving grace occurs the moment you accept our lord, that is sufficient.
