Faith is not sufficient for salvation. Period. It's is essential it is necessary it is needed but it is NOT sufficient for salvation because if it were it wouldn't need completion by works. Please stop this silliness if yours.
Faith doesn't - and can't - save anyone. Only Jesus saves (
Jn. 1:4, 12; 14:6; Ac. 4:12; 1 Ti. 2:5). But our faith in Christ
puts us into position to be saved by him (
Jn. 3:16; Ro. 10:9-10); it's how, in part, we "draw near" to God (
Ja. 4:8).
Good works don't save us, either. All of our works are tainted by our natural selfishness and sin and cannot ever meet God's standard for acceptance which is His own perfection (
Matt. 5:48). And so, we read in Scripture:
Ephesians 2:8-9
8 For by grace you have been saved through faith; and that not of yourselves, it is the gift of God;
9 not as a result of works, so that no one may boast.
2 Timothy 1:9
9 who has saved us and called us with a holy calling, not according to our works, but according to His own purpose and grace which was granted us in Christ Jesus from all eternity,
Titus 3:5-7
5 He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy, by the washing of regeneration and renewing by the Holy Spirit,
6 whom He poured out upon us richly through Jesus Christ our Savior,
7 so that being justified by His grace we would be made heirs according to the hope of eternal life.
Jesus is perfect for us, fully satisfying God's holy justice, "once for all" atoning for our sin (
He. 7-10:22; 2 Co. 5:21). There is nothing more God requires of us in order to adopt us as His own. What, then, of works? They are, as the apostle James explained, the natural consequence of one's faith in Christ. Just like an apple tree naturally bears apples, so, too, a genuinely born-again child of God (
Jn. 3:3-7) naturally produces works that correspond to their belief in God's Truth. But no one would say that an apple tree that isn't bearing apples is not an apple tree. It could be too young to do so, or in poor soil, or starved of sufficient moisture, or sickened by pests or disease. Any number of things can prevent an apple tree from bearing apples. And so, no reasoning person would say the absence of fruit on an apple tree negates that it's an apple tree.
In the same way, no person taking God's word as it is, would think that the
natural by-product of being saved - good works - are
necessary to being saved. As the apple tree demonstrates, what is
natural - bearing fruit - is not also
necessary. For any number of reasons, a truly born-again person may not bear "fruit" in their living. They may be very new to the faith; they may be badly taught, or not taught at all; they may be sickened spiritually by false teaching, or be suffering from the "pests" of various besetting sins, well-established habits of thought and deed that cannot be immediately dissolved; they may be very physically ill, or enduring some terrible tragedy. And so on. Very often, a combination of these things hinders a saved person, making it doubly or triply difficult to produce "apples" of good works. As well, the devil gets in on all of this, exaggerating and aggravating whatever is stifling "fruit production" in the life of the saved person (
1 Pe. 5:8).
Because this is the case, because various impediments can mound up around a Christian person stifling their "fruit production," we see in the NT many letters of instruction, and rebuke, and exhortation of Christians who are so stifled:
- The "carnal babes in Christ" of 1 Corinthians (
1 Co. 3, 5, 6, 11).
- The believers of the province of Galatia straying into law-keeping legalism (
Ga. 3:3).
- The sinning Christians at Rome who did not understand the full import of their union with Christ (
Ro. 6-8:16).
- The five churches of Asia Minor guilty of much compromise and sin (
Rev. 2-3).
So, no, our good works, though natural to being a child of God are not, therefore, necessary to being His child.
