One: Salvation is ~truly~ by faith alone, through grace alone, in Jesus alone. (John 6:47; 1st Corinthians 15:1-4.)
Salvation (Guaranteed entrance into Heaven) is NOT by repentance of sins, not by commitment to Christ, not by your continued good works throughout your lifetime, not by water baptism, not by regularly taking the Lord’s Supper, not by regular church attendance, not by abstaining from big sins, not by confessing or repenting from sins, and not by being a “good person.” These are all fine good works, but they are NOT to be relied upon for salvation.
Salvation is by faith in Jesus alone (John 6:47; first Corinthians 15:1-4. Yes, I repeated those. Please look them up.)
Eternal Security for the believer in Christ is biblical. (Ephesians 1:13,14)
Two: Eternal Sanctification is received through believing in Jesus. It is received at the moment of belief in Jesus as Savior, crucified for all of your sins, dead, buried… and resurrected from the dead on the third day.
Believers are eternally and perfectly righteous in Christ.
Practical Sanctification, or growing in grace, or growing in Christ, imperfect though it is, on the other hand, is through willing God’s will by His grace and spirit, as well as living by grace, by faith, by living in His love, living by His Word, and imperfectly living by our perfect, righteous identity in Christ.
Perfect Sanctification is given to us in Christ at the moment of saving faith.
Practical Sanctification is daily trusting what Jesus has done for us, and living in faith that those things are true.
Practical sanctification is not trying to be accepted by God through our “good” works. Our good works are imperfect filthy rags, according to the Bible.
Believers have perfect acceptance with God through faith in Christ.
Practical Sanctification is relying on what Christ has done for us: perfect, free, and finished.
Three: water baptism is obsolete. The true baptism is being baptized into the death and resurrection of Christ.
Paul said that he came not to baptize (with water).
John the Baptist said that he baptized with water, but One would come after him who would baptize with the Holy Spirit (Jesus).
Four: Inclusivism. The Bible says that God has ways to save people through Christ alone that don’t involve them having a rational thought process, don’t involve them knowing the Name of Jesus.
Some people outside of God’s chosen groups are saved; and some people within the churches and seemingly within His groups are not saved.
There are examples in the Bible:
Rahab and the Spies in the Old Testament.
John the Baptist in the womb, rejoicing, having faith in Jesus, as a fetus.
David on his mother’s breast, an infant with faith.
Adam, Abraham, Noah, Moses, David, Isaiah and thousands of others did not know the Name of Jesus until after their deaths, but they certainty are saved, and the Bible says they are.
And all of the tribes, tongues, peoples and nations saved in the end, many of which have never heard the Name of Christ–there will be people from all these groups in Heaven, and the Bible says this, too.
Inclusivism, NOT universalism, and NOT salvation through other religions, and understood this way, is certainly biblical.
Five: Experiencing Personal Communion with God. This is experienced by His grace, by faith, by His Spirit, through His Word, by prayer, by meditation on God and His Word, by devotion, by seeking God’s close presence, by living in His love, by willing His Will, and by obeying His commands and by following His Spirit.
