1 Peter 1:13
 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. (ESV)
Here we have the word, "therefore." When we see this word in Scripture we look at the preceding verses so that we know what "therefore" is there for. Peter has just expounded on how wonderful our salvation. It was prophesied by prophets of old. The apostles taught it. Even the very angels of heaven longed to look into our salvation. We have something that is wonderful. We have been saved by the grace of God.
Therefore, in light of our wonderful salvation, we should prepare out minds for action, being sober-minded, setting our hope fully on the grace that will be brought to us at Christ's return. It seems there is a tendency of Christians to sit on their hands, waiting for the return of Christ. They are lulled to sleep and inactivity by the allurements of the world around them.
Peter says that we are to prepare our minds for action. The first step in preparing our minds is to get rid of the distractions that keep our minds from focusing on bringing the gospel to the world. We live in a world full of things that demand our attention. There are now more entertainment options on your television, smart phone, tablet, or other electronic devices than one can possibly keep up with.
Not only do we need to put aside the things that are distracting us, but we need to do intentional things that will prepare our minds. Our minds are prepared for the action as we fill them with the Word of God. If we do not know Scripture we will certainly not know how to communicate the truths of our wonderful salvation to the world around us. We need to take this seriously.
How sober-minded are you? What distractions do you need to set aside so that you can fill your mind with the truths of God's word. God's salvation is so wonderful that we need to take action to share it with others.
