How do we know that Christ's exaltation is true?

We can be assured of Christ's exaltation through the testimony of Scripture and the apostolic witness found in the New Testament. In Acts 2:30-36, Peter preaches that God has raised Jesus up, and being exalted at the right hand of God, He has poured out the Holy Spirit. This witness of the apostles, who were eyewitnesses of the resurrection and received the Holy Spirit at Pentecost, confirms that Jesus is indeed exalted and sovereign. Additionally, Paul's writings throughout the New Testament repeatedly affirm Christ's lifted status, emphasizing His dominion over all powers and authorities in both this age and in the age to come.
