Is believing and obeying God from the heart 'effectuating' our salvation, and so we shouldn't be doing that? We should avoid doing anything that draws us closer to God, because that would be 'effectuating' our salvation?
If we believe from the heart, it can only be because we have first been given that belief from God as a gift. True biblical belief comes from God to each of those saved.
[Gal 5:22 KJV]
22 But
the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness,
faith,
[2Co 4:4 KJV]
4 In whom the god of this world
hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
[1Pe 1:21 KJV]
21 Who
by him do believe in God, that raised him up from the dead, and gave him glory;
Confessing with our mouths the Lord Jesus is certainly an effectual work to be saved by. There are many in the world who have not the power to do that work, and so they cannot confess Him.
No one can truly confess with the mouth until the heart is changed, but only God can change the heart. A change of heart must come first.
[Eze 36:26 KJV] 26
A new heart also will I give you, and
a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
[Heb 10:16 KJV]
16 This [is] the covenant that I will make with them after those days, saith the Lord,
I will put my laws into their hearts, and in their minds will I write them
ut as many as received him, to them gave he power to become the sons of God, even to them that believe on his name.
Salvation and justification with God is a walk with God, a fellowship with God.
It takes two to tango.
[Jhn 6:37, 44 KJV]
37 All
that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. ...
44
No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
[Jhn 6:29 KJV]
29 Jesus answered and said unto them,
This is the work of God, that ye believe on him whom he hath sent.
If we are not doing our part to work out our own salvation, then we have no part in His body, not in His first resurrection of the saints.
So, you just let whatever thoughts come into your mind and just do them, because you have no rule over yourself? You just do whatever your mind and body want to do?
First, as unworthy sinners, God through His mercy and grace, saves in spite of all that we are/were. From that salvation,
He gives a renewed spirit and mind. By that renewal do we come to comprehend, believe in and adopt true Christian attributes - not before
[Eph 4:21 KJV]
21 If so be that ye have
heard him, and have been taught by him, as the truth is in Jesus:
[Eph 4:24 KJV]
24 And that ye put on the new man,
which after God is created in righteousness and true holiness.
[Col 3:1 KJV] 1
If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God.
[Col 3:10 KJV]
10 And have put on the
new [man],
which is renewed in knowledge after the image of him that created him:
And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.
And the times of this ignorance God winked at; but now commandeth all men every where to repent.
Who repents for you? God? God doesn't need to do any repenting.
Even though it is a command, no one can truly repent from dead works unless and until that repentance is given to them from God. To those who do it is/was a gift, to those who do not, it is condemnation against them.
For those who Christ came to give salvation to, He has repented to the Father on their behalf. Because of that, do they
themselves repent from their dead works unto faith in Christ.
Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.
The "a man" in that verse is Christ. Should we choose to boast of faith - that it is of ourselves- then it better have the works that Christ's faith had - which is/would be impossible. True faith has works at its core, but only Christ could produce true faith AND works to please the Father. We have been "shewed" (demonstrated), Christ's works and His faith in that He alone satisfied the Father's requirement. Christ's faith is reckoned to those He saves. Our faith does not produce salvation - instead it is given as a gift by God as a part of salvation. God is the Saviour, we are not.
