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.
1 Peter 1:13 (ESV)
To be sober-minded is to be filled with what the Word declares over us. It is to keep our minds actively focused on the truth of God’s Word, and to be actively on guard against the lies and deceptions of the enemy that would seek to invade our thinking. Our confident assurance is set fully upon what the grace of God has made available to us in Christ Jesus.
