I can understand your disagreement, Wing, but let me walk you through this a little more closely:
Even if someone tries to earn a gift, the gift of salvation is still given. It is heretical to teach that one must do good works to earn salvation for that is clearly wrong, but if someone tries to out of ignorance they aren't rejecting the gift.
This is simply wrong. It is logically impossible to both trust Christ and my works for salvation. If I am trying to work my way to heaven, then I am not accepting grace. Paul makes this point very clear in Romans 11:6, saying, "And if by grace, then it is no longer by works; if it were, grace would no longer be grace." (NIV)
Notice also Eph. 2, which you quoted. Yes, we are saved THROUGH faith, but we are saved BY grace. Faith is not the thing that saves, as you know. Grace is. Grace, by definition, is unmerited favor. It must be received as a gift. A true statement is this: "God saves by grace or not at all."
Consider this analogy. Suppose you were to offer someone a gift, and as soon as you did, they pulled money out of their pocket. Now, if you accept the money in exchange for the gift, then the gift is no longer a gift. We certainly don't think the gas we buy every day is a gift! No, the moment someone pays for something, even in part, it is no longer a gift. In fact, you would probably be offended if someone refused your gift, but instead insisted on paying you for it--especially if this is someone you dearly love and this is something you really want them to have!
Again, Paul makes this point clear in Romans 4, saying:
- Now when a man works, his wages are not credited to him as a gift, but as an obligation. However, to the man who does not work but trusts God who justifies the wicked, his faith is credited as righteousness (Rom. 4:4-5, NIV)
Now, faith alone is the condition on which the gift of salvation is received. But, it MUST be received by faith ALONE. If a person attempts to "help" God, be it in ignorance or not, then they have not accepted the free gift of grace.
Also, you mention other isses:
Also, you mention baptism as one of these rejecting works. Baptism (like the Lord's Supper) is a means of grace. It is a way that God bestows on us his grace of forgiveness and salvation. It is recieved in faith. If you go to the fount and don't believe, you won't recieve the grace. A believer, however, does.
I disagree that it is a means of grace . . . particularly not a means of saving grace. We are not regenerated, justified, forgiven, or anything else of that nature by baptism or by the Lord's Supper. I invite you to show me a single place in Scripture where this is taught. My Bible clearly says that salvation is by grace through faith . . . grace is not applied through baptism or the Lord's Supper. They are absolutely never connected to eschatological salvation.
Now, I say again, if you believe that baptism is necessary for salvation, then what you are saying is that
Christ alone is not enough! You are, in fact, calling Christ a liar, for He said, "He who believes in me has everlasting life." There are over 100 verses that say explicitly that faith alone is the necessary condition for salvation. To add to that is to
reject the promise of Christ.
So why do baptism and the Lord's Supper if all we have to do is have faith? Well first off, God commands us to do those things. That is what a sacrament is. A sacrament is a practice that both bestows upon us the grace of God and that it has been instituted by God.
Before I answer this, I want to point out the phrasing of your question to show how very dangerous the theology you are proposing is. You said, "So why do baptism and the Lord's Supper if
all we have to do is have faith?" The obvious implication here is that we have to do
more than have faith! Therefore, when Christ says to have faith in Him to be saved, you are saying to Him, "No, Lord . . . You are mistaken. I have to have faith, but I also have to be baptized and receive Your supper." You, thus, reject His offer.
Jesus saves on HIS terms and HIS terms alone. There is no other option with Him. You receive the gift of salvation freely, or you do not receive it at all.
Why, then, should we do the things mentioned? Because Christ told us to. They are part of the sanctification process. In baptism, we identify ourselves publically with Christ. The Lord's Supper is a reminder of His Covenant with us, much as Passover did for the Jews of old. We could take this much deeper and get into the theology of the covenant and its initialization, if you like. That would take us all the way back to Genesis. But, I hope this suffices for the time being.
God bless
