How does Les describe the power God worked in Christ when He raised Him from the dead?

This tremendous, all-consuming power is the resurrection power God wrought in Christ when He raised Him from the dead. Resurrection is the epitome, the high point of everything God has accomplished, and without it everything else falls apart. It is the power that raised Christ and set Him at God's right hand in the heavenlies.

Les explains that the power God worked in Christ is the tremendous, all-consuming power by which He raised Christ from the dead. He ties this to I Corinthians 15 and stresses that resurrection is the epitome, the high point of everything God has accomplished. If there were no resurrection, everything else would fall apart, just like a cloud on a hot summer day. He notes that God the Father, together with God the Spirit—the triune God—raised Christ and set Him at His own right hand in the heavenlies. Jesus did not set Himself there; an outside personage did this, as also seen in Hebrews chapter 1.

Ephesians 1:20

Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places,

What did God do with Christ after raising Him from the dead?

Scripture teaches that after raising Christ from the dead, God set Him at His own right hand in the heavenlies. This position was assigned by God the Father, not self-appointed, demonstrating Christ's exalted place. The triune God raised Him and set Him there, as an outside personage.
