"who teaches how you & I are JUSTIFIED/saved ?"

By faith, so if you loose that faith, you naturally loose justification.
Justified by faith in believing in the shedding of Jesus's blood.

Rom 5:9 - Much more then, having now been justified by His blood, we shall be saved from wrath through Him.
3:25 - God presented Him as the atoning sacrifice through faith in His blood,

2 Tim 2:11,12 - This is a faithful saying: For if we died with Him, We shall also live with Him.
If we endure, We shall also reign with Him. If we deny Him, He also will deny us.

Endure in faith.

Phil 3:9 - and be found in Him, not having my own righteousness, which is from the law, but that which is through faith in Christ, the righteousness which is from God by faith;

If you loose, drop your faith = no righteousness, so there is no once saved always saved there.

These are just a few of many.
