NO! there are two keys first one is belief in Christ, kind of like looking through a skeleton key hole in a door, and as you look through the whole there you know is beauty on beyond this door, so you ask God for salvation and Jesus takes the key and opens the door, you are justified, sanctified, made forever holy as you step through the door, and God starts performing the work through you that you , I and all believers need, teaching us truth that sets us free, it all boils down to love that is unconditional.
The second key is works, 1 Cor. 3, either my works are going to nurn up or they will not it depends on what the works are built out of, wood, hay, stubble, which is all flesh works or gold which is pure. 1 Cor.3 :10-15
10 By the grace God has given me, I laid a foundation as a wise builder, and someone else is building on it. But each one should build with care. 11 For no one can lay any foundation other than the one already laid, which is Jesus Christ. 12 If anyone builds on this foundation using gold, silver, costly stones, wood, hay or straw, 13 their work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each person’s work. 14 If what has been built survives, the builder will receive a reward. 15 If it is burned up, the builder will suffer loss but yet will be saved—even though only as one escaping through the flames.
So the only way is belief, there are no additions to salvation, the things man has added are for man's gain and has done a great job at it, but God is not deceived nor mocked, and God loves us all the same hoping all come to the dinner feast with a white robe given to us, never ever earned, We get rerwarded by God for saying God please do not just live in me, but more importantly through me, and God's works through one the believer will never burn up.
Now to understand the works issue works is a by-product of faith in Christ Jesus. If Abraham did not believe God then Abraham would not have done the work. If Jesus did not represent God the Father then Jesus would not have done the work. Jesus did nothing without Father telling him. We are to learn the same and get out of worldly traditions. keep growing in grace, God will straighten out all the errors in each and every one of us that believe in Christ Jesus
It takes personal study, as like if you were to become a bank teller,you would get so familiar with the money that as soon as counterfeit showed up you would know it immediately. So in knowing God or getting to know God who would have to be your teacher in order to know counterfeit as soon as it passed by? Answer is in Hebrews. There are too many denminations for any of those to be perfectly correct. So the only truth that is truth comes from the creator period, and the creator God will reveal truth to anyone that truly wants to know him all the rest are fakes. They are like the serpent at the tree of evil causing doubt and Adam And Eve ate there from. There is only one God, one faith one Lord and one baptism. The believers are also a part of this one, for 1x1x1x1x1 always equals one
Hoping this helps in your walk
