What does 1 Peter 5:11 mean?

Before officially signing off in the following few verses, Peter concludes the substance of his letter with a benediction. This is a type of blessing which often comes at the end of a service or sermon. In this case, the blessing is offered to "the God of all grace" mentioned in the previous verse.

In addition to blessing God, Peter's benediction reflects a simple fact: all of the power and dominion in the universe belong to God, both now and forever more. He will not fail. He will not yield. He will accomplish every purpose according to His own will and in His own time.

For those facing persecution for their faith in Christ, that fact alone offers enormous comfort. The previous verse promised that the God of all grace will restore, confirm, strengthen, and establish us following this life of suffering. Here, the statement that He will always have the power to follow through on that promise is an anchor for every hurting believer. It is the reminder we need to stay firm in our faith in Him during hard days.
