Salvation by grace of God and salvation by the good works of man will always conflict, unless you can understand that all of the scriptures that use salvation in them are not referencing eternal salvation. Salvation according to Greek means = "a deliverance". Many of the scriptures, such as you have quoted, pertaining to salvation are talking about deliverances we receive here in time and are not depicting eternal deliverance. This is the main reason that babes in Christ, who are still on the milk of the word and are not able to digest the meat of the word, are persuaded to believe in eternal deliverance by their good works, such as believing and confessing.
Actually, the scriptures I quoted pertains to
SALVATION, NOT healing or deliverance.
No one gets healed or delivered by simply believing God the Father raised Jesus from the dead and confessing Him as lord.
That is not how faith works for one to be saved, nor is it how the kingdom of heaven/God works.
You can't call and look for the cat and expect the dog to show up.
Faith doesn't work that way.
The Greek word translated as "saved" in many texts, means more than just delivered. It also means to save, that is, deliver or protect (literally or figuratively): -
heal, preserve, save (self), do well, to
be (or make) whole.
It's an all-purpose all-rounder cure-all or panacea.
It covers your whole spirit, soul, and body.
Concerning good works, I would suppose it depends on what you define as a good work.
I'm assuming it is not the same "good works" Jesus did, such as, healing the sick, raising the dead, and the like, but that of the works written in the law, such as, giving to the poor, going to church, reading the bible, and the like.
The kind of works Jesus did will glorify God, and the latter works written above will only glorify the people themselves.
The former works are works of faith, and the latter are more like moral works of the law.
The former works, we CANNOT do, or are incapable of doing, of our own power, strengths, or abilities, but the latter we can do of our own power, strengths, or abilities.
Works of faith REQUIRE the believer to do a correspond work to said belief, for God to move in the situation.
The end result with no work or act done in faith, will be,
nothing happens or a negative result. There will be NO salvation, deliverance, healing, or answered prayer without an act or work done in faith.
The natural man, before he has been born again with the indwelling of the Holy Spirit, cannot discern the things of the Spirit in order to believe and confess. After we are born again, there is a deliverance we receive here in time when we confess and believe. Can you not see, with this understand, that God gets the glory and not man?
Perhaps you don't fully understand just how this believing and confessing thing works.
Why do you think the bible says, both death and life is in the power of the tongue, and they that love it, shall eat the fruit thereof?
The law of faith or WOF, is a universal law.
It works for both the child of God and unbeliever, for both good and bad, blessing and cursing.
Most people, both believer and unbeliever, either bless or curse both themselves and their family, unwittingly, by speaking what they believe, by speaking either words of faith, which can be for good or bad, or words of fear, which is a belief in the possibility of something bad transpiring or an expectation of a negative outcome.
Why do you think Jesus said, regardless of who you are, you will be judged by EVERY IDLE or THOUGHTLESS word you speaK?
And why do you think Jesus said, a good man brings forth good things and an evil man brings forth evil things based on the treasure stored up in their hearts that they spoke with their mouth?
It is because the spiritual laws of God rule and work, over and in, this natural world we live in, through both the believer and nonbeliever.
So the nonbelievers or natural man, use the spiritual laws of confessing what they believe, or speaking words of faith, albeit unwittingly, causing either a blessing or cursing in their lives.
And the same goes for the believer as well. We are a product of what we have said or spoken without thought.
The purpose of preaching the good news or gospel of Jesus Christ, is because, it is written, "faith cometh by hearing..."
Once a person hears the gospel of Jesus, they are capable of discerning, understanding, and believing the spiritual ramifications of rejecting Christ, and the blessing of accepting the same.
This is not the same as believing in Santa Claus, where we stop believing once we grow up.
If a young child can do it, so can the adults.
