Save by ...?

Some of the list and question that I opened up for a discussion to know about salvation and how are we gonna define BEING SAVED?

Matthew 7:21 ¶ Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that DOETH THE WILL OF MY FATHER which is in heaven 

• Which means there we're works need to be done...

Philippians 2:12 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.

• What needs to be workout if I'm already saved?

16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:

17 That the man of God may be perfect, throughly furnished unto all good works. (2 Timothy 3)

I understand that the scripture helps us learn abouts God's Goodness and we are already saved, so what's good works are for?

7 That being justified by his grace, we should be made heirs according to the hope of eternal life.

8 This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to MAINTAIN GOOD WORKS. These things are good and profitable unto men. (Titus 3)

• Of course, we are justified by his Grace, so why do we need to carefully maintain GOOD WORKS?

Christ simple words in which said this -

John 14:15 If ye love me, keep my commandments.

Keeping the commandments is not just by studying it, Application is necessary, and what I mean by application is simply working it out. There's no such thing as Salvation without something that needs to be done. Which means Christ words need to be applied or kept such commandments as loving our neighbours, do good to them, help the needy, observe the Sabbath and the list goes on, which basically the commandents and laws that God gave to man. So why do I maintain GOOD WORKS? Christ tolds me so, that's why I work out for it.

Another thing is, if we go along to the next verse that says this -

16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;

17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.

18 I will not leave you comfortless: I will come to you. (John 14)

So, what's with this verses for if I'm already saved? Why would I need a comforter that will abide with me forever if I don't need it in my salvation? What's the use of it after I accepted Christ as my Saviour, Lord and God (which is the only thing that needed for my salvation)?

To Christians who were saved by just simply saying "we're saved". How are you gonna reconcile that using your ideology?
