James 4:17, "Therefore to him that knoweth to do good, and doeth it not, to him it is sin."
Serves as a powerful reminder of the responsibility believers have to act in accordance with God's revealed will. This verse highlights that knowing what is right and failing to do it is considered sin. This is a call to active obedience and a life of holiness, emphasizing that faith must be demonstrated through righteous actions.
In the context of salvation and daily living, this principle underscores the importance of adhering to the teachings and commandments found in Scripture. It implies that once a believer understands God's expectations—such as the necessity of repentance, baptism in Jesus' name, and receiving the Holy Spirit—they are accountable for acting on that knowledge. Ignoring these revealed truths or failing to live by them constitutes sin because it is a deliberate neglect of God's instructions.
This verse challenges believers to diligently seek God's will and to live it out consistently. It reinforces the concept that genuine faith produces a transformed life characterized by obedience to God's Word. Therefore, James 4:17 is a compelling exhortation to not only believe but also to actively do what is good and right according to the knowledge of God's truth.
If we're going to "act in accordance to God's revealed will" as you say, then why does Oneness theology not baptize in the name of the Father, the Son, and the Holy Spirit as God's Word has plainly stated?
The mistake is following a second hand account of what Luke wrote in the Book of Acts, rather than the direct instructions given to Paul and then given to us by Christ.
The Book of Acts in not instruction, it's the account of what happened, and is so often misunderstood. That's why Christ gave us Paul with his 13 epistles (that's if you count Hebrews).
