That begins with speaking this first truth: I belong to God my Father and my faithful Savior, the Lord Jesus Christ. Belonging is powerful in and of itself. But belonging to the Most High God, who is the one true living God and the Creator of all things, gives us peace and assurance that is not of this world. In fact, it is out of this world. Ephesians 1:3–14 speaks to the gifts received by those in Christ as “every spiritual blessing in the heavenly places” and tells us our triune God—Father, Son, and Spirit—has worked together to secure our union with Him. This kinship (Rom. 8:15), which comes with such great benefits, leads us then to that famous heart song, “I am His, and He is mine!” Nothing can take that truth away. This is not a feeling that wanes or a fancy that fades over time. It is a surety that we can solidly rest upon. While we are resting on that truth, we lean in under the yoke of Christ and strive to live for Him with the grace He provides. As we speak the truth of who we are to ourselves, our hearts and lives are transformed. Our hearts become galleries that display living portraits of His gospel of grace “to the praise of His glory” (Eph. 1:14).
This may be why the first question and answer of the Heidelberg Catechism embodies this all-important first truth:
What is thy only comfort in life and death? That I with body and soul, both in life and death, am not my own but belong unto my faithful Savior Jesus Christ who with his precious blood has fully satisfied for all my sins, and delivered me from the power of the devil and so preserves me that without the will of my Father, not a hair can fall from my head, yea, that all things must be subservient to my salvation, and therefore by His Holy Spirit He also assures me of eternal life and makes me sincerely willing and ready henceforth to live unto him.
Did you hear the rewards of knowing you belong to our great triune God? Comfort, justification, deliverance from the evil one and his power, preservation in all things unto the glory of your eternal salvation, and even the disposition through the Holy Spirit to live for Him for now and evermore. These spiritual blessings form the foundation of our identity in Christ.
When our hearts deceive us and try to convince us that hanging onto guilt, which has already been placed on Christ, is even remotely acceptable, we must stand our ground. We must declare these truths to ourselves once again. “There is, therefore, now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life has set us free from the law of sin and death” (Rom. 8:1–2). We are free indeed. With grateful, humble hearts, we are free to rest on the yoke of our Savior and all that it means to be His. Our freedom transforms our resting into life-giving service to Him in all our responsibilities: loving our husbands and children, sharpening iron with a friend, being a champion for our disabled child, crying with someone who’s hurting, caring for an aging parent, and yes, leaning harder on Christ when storms rage within our hearts. Rest is ours.
This Jesus, to whom we belong, will not waste anything in our lives as He transforms our hearts into lowly hearts like His, and He is just as faithful to provide all we need for that transformation. Rest in Him.
