“Therefore, preparing your minds for action, and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ” (I Peter 1:13).
The word “therefore” (διό; dio) means “for this reason.” It is a conclusion. Peter draws a conclusion or deduction from what he has previously written in 1:1-12, and which indicates what will now be the focus of what is contained in the rest of his epistle.
In light of all of which Peter has stated the believer is and possesses in Christ, while even in the midst of suffering, he calls believers to prepare their minds for action. To prepare (ἀναζώννυμι; anazonnymi) our minds (διάνοια; dianoia) for action (ὀσφῦς; osphys) is our responsibility. Peter uses three words which essentially have the same meaning. Believers are to get their minds ready for action. In other words, we are to get what Peter has said, and will say, through our heads or into our thinking. We are to prepare ourselves for learning.
God wants His children to understand and apply what He has revealed to them in His Word. Following Christ is not about fun, games and frivolity. The Christian life is about living for the glory of God and being holy in everything we do. This is a serious concern for the Apostle Peter and should be for you and me.
God calls us to be sober-minded. This means to be self-controlled and restrained in our behavior. We are called to not have irrational thoughts, but rather minds guided by the Spirit of God through the Word of God. This is so God will help us to progress in the grace relationship He has established with us, which ultimately will be fulfilled and completed when Jesus Christ returns to earth in His power and glory.
Each day we have the opportunity to prepare ourselves for action in progressing in the covenant relationship we have with God in Christ. This means to become more holy today than we were yesterday and to be more holy tomorrow than we are today. We are to take this seriously because holiness is serious business with God. Press on, beloved.
Soli deo Gloria!
