How do we know that faith must be in the name of Jesus?

The Bible consistently emphasizes the necessity of faith in the name of Jesus for acceptance before God. Passages like Acts 2, when Peter calls for baptism in the name of the Lord Jesus Christ, affirm this principle. Additionally, Zephaniah 3:12 highlights that the afflicted and poor people of God will trust in His name for their salvation. Thus, placing faith in the name of Jesus signifies our reliance on His redemptive work, underscoring that without Him, our actions lack merit before God.
