Why is believing in the name of Jesus important for Christians?

The name of Jesus embodies His power, authority, and accomplishments regarding salvation. As stated in Philippians 2:9-11, God has highly exalted Him and bestowed upon Him a name above every name, ensuring that at His name every knee should bow. This signifies His authority over all creation and the ultimate recognition of His lordship. Believing in the name of Jesus symbolizes trust in His finished work on the cross and acknowledges Him as the only source of salvation. It not only solidifies our relationship with Christ but ensures that we are part of the identity of the church as His called-out ones. Thus, His name is central to Christian faith and practice.
