Therefore gird up the loins of your mind, be sober, and rest your hope fully upon the grace that is to be brought to you at the revelation of Jesus Christ. (1 Peter 1:13 NKJV)
Gird up the loins means to gather your long robes with a belt to prepare for action (for a battle); but this verse is talking about the mind being prepared for action. We’re to be sober which means temperate, restrained, serious, thoughtful, calm, and unruffled.
We can be calm and tranquil because the revelation of Jesus has already occurred! His work is finished! Praise our God!
We’re instructed to rest our hope (confident expectation) upon the grace given to us at the revelation of Jesus, our Savior. We’re so highly blessed to be among those who have received this sacred revelation!
We may rest confidently upon His grace. We may rest, knowing that our salvation was paid for fully by Jesus. There is no work or striving that we need to do, but just to live our lives for Him by the grace that He has already provided.
. . . through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God. (Rom 5:2)
. . . that having been justified by His grace we should become heirs according to the hope of eternal life. (Tit 3:7)
In the Bible, the Lord is shown again and again to be our defense in times of trouble or difficulties. Defense means protection, security, cover, or shield. It can also mean justification or vindication. Assuredly, Jesus Christ is our justification!
My defense is of God, Who saves the upright in heart. (Ps 7:10)
I will wait for You, O You his Strength; for God is my defense. (Ps 59:9)
He only is my rock and my salvation; He is my defense; I shall not be greatly moved. (Ps 62:2)
But the Lord has been my defense, and my God the rock of my refuge. (Ps 94:22)
The Lord is our protection; and this is something that we all need to recognize and to trust in, since we live in an increasingly hostile world—one that is growing even more antagonistic to the message of the gospel. Let us remember to confess, along with the Psalmist, “My defense is of God.”
It is essential for us to remain in a strong and vital relationship with the Lord. The Word of God feeds us and increases our faith. It reminds us who we are and of the One we serve. Don’t allow yourself to become complacent, or to wander away from daily Bible reading and contemplation.
Continue to worship with other like-minded believers on a regular basis because we’re encouraged to have fellowship with our brethren. (Heb 10:25) As we fellowship with other believers, they will support us and encourage us, spurring us on to good works! Glory to God!
