“That at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth”
Since Christ has been exalted, the nature of worship has changed. All worship focuses on Jesus Christ.
“that at the name of Jesus every knee should bow”
Not “at” but “in” the name of Jesus. This is not mere genuflection. This is reverent worship. Jesus is the object of our worship.
Note the word “every” in “every knee should bow.” This is universal subjugation, not universal salvation. The Bible teaches that one day every individual will face the Lord Jesus. When that happens, every knee will bow in acknowledgment of His Lordship. All will acknowledge Him as King Jesus. They will concede to His right to sovereignty.
The word “that” introduces a purpose clause. The Father glorified Christ for a purpose—that all creatures might worship Him, both angelic and human.
“of those in heaven”
“Of those in heaven” refers to angels and people who have gone to heaven.
“and of those on earth”
“Those on earth” refers to human beings who are alive in time.
“and of those under the earth”
“Those under the earth” probably refers to fallen angels.
Jesus has the right to absolute sovereignty over our lives.
In view of the fact that we will one day concede to His sovereignty, why not begin now? If you are not a Christian, there will be a day when you will see His majesty and rights in a clear light. If you are a Christian with rebellion in your heart, why not submit that area of your life to Him now?
