Then you don’t need grace since you aren’t required to do anything. That’s wrong.
The New Testament says you need grace. Once you understand why you need grace, you’ll realize because it’s your safety net to make mistakes without punishment with the expectation you’re still going to continue walking in the Spirit and not gratifying the works of the flesh.
There’s no law against the fruits of the Spirit, hence someone is under grace. However, there are laws against the deeds of the flesh, hence why those things can cause someone to fall from grace, become under law, and not inherit the kingdom of God.
Galatians 5 says all of this.
This means you have work to do. Faith + works. That’s my belief and I’m sticking to it.
These 1st 6 verses shared in the OP disagree with your Faith + works narrative:
These last 2 verses couldn't make Faith & Faith Alone clearer:
Rom 3:
21 But now the righteousness of God has been clearly revealed [independently and completely] apart from the Law, though it is [actually] confirmed by the Law and the [words and writings of the] Prophets.
22 This righteousness of God comes through faith in Jesus Christ for all those [Jew or Gentile] who believe [and trust in Him and acknowledge Him as God’s Son]. There is no distinction,
23 since all have sinned and continually fall short of the glory of God,
24 and are being justified [declared free of the guilt of sin, made acceptable to God, and granted eternal life] as a gift by His [precious, undeserved] [c]grace, through the redemption [the payment for our sin] which is [provided] in Christ Jesus,
25 whom God displayed publicly [before the eyes of the world] as a [life-giving] [d]sacrifice of atonement and reconciliation (propitiation) by His blood [to be received] through faith. This was to demonstrate His righteousness [which demands punishment for sin], because in His forbearance [His deliberate restraint] He passed over the sins previously committed [before Jesus’ crucifixion].
26 It was to demonstrate His righteousness at the present time, so that He would be just and the One who justifies those who have faith in Jesus [and rely confidently on Him as Savior].
These last 2 verses couldn't make Salvation comes via Faith & Faith Alone:
Acts 10:
44 While Peter was still speaking these words, the Holy Spirit fell on all those who were listening to the message [confirming God’s acceptance of Gentiles].
(MY NOTE: As Peter spoke, (Faith comes by hearing - Rom 10:17) those hearing believed)
45 All the circumcised believers who came with Peter were amazed, because the gift of the Holy Spirit had been poured out even on the Gentiles
(MY NOTE: Thru faith alone, regeneration/Christ's salvation sealing/eternal life giving Holy Spirit (2 Cor 1:22, 5:5, 2 Tim 1:14, Eph 4:30) was/is given!)
Posted passages proclaim Salvation/Eternal Life is given via faith in the merits/work/sin payment & resurrection of Christ. Also see 1 Jn 2:2 & 1 Jn 4:10
Additionally:
Rom. 3:24 and are being justified [declared free of the guilt of sin, made acceptable to God, and granted eternal life] as a gift by His [precious, undeserved] [c]grace, through the redemption [the payment for our sin] which is [provided] in Christ Jesus,
(MY NOTE: Justification is a God given GIFT, accessed thru faith place in Christ's sin atoning sacrifice)
Rom 5:
17 much more they which receive abundance of grace & the of "gift of righteousness" shall reign by one, Jesus Christ
18 Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one "free gift came upon all men unto justification" of life.
(MY NOTE: Righteousness is a "FREE GIFT". Given by God to those that trust in the Lord Jesus sin atoning death & resurrection.
A GIFT is given, NOT, worked for/earned!
