Understanding Our Blood Covenant in Christ: A Foundation for Unshakable Faith

Welcome to another episode of the Health for the Spirit, Soul, and Body Blog from Doxa Missions. Today, we’re looking at a powerful truth that many believers know about but may not fully understand—our blood covenant in Jesus Christ. This foundational truth has the power to transform how we see God, how we view ourselves, and how we live out our faith every day. 

What Is a Covenant, and Why Does It Matter? 

A covenant is more than a promise. It’s a binding agreement between two parties, pledging mutual commitment, loyalty, and action. In biblical terms, a covenant often involved blood, signifying its seriousness—something not to be broken. 

Covenants were common in ancient cultures, but in Scripture, they take on divine meaning. They are God’s chosen method of expressing His unchanging nature and His unwavering commitment to His people. Understanding our blood covenant in Christ gives us boldness and assurance in our relationship with God. 

Abraham: From Uncertainty to Covenant Faith 

When we think of Abraham, we often think of him as the “father of faith.” But he didn’t start there. In fact, when God first called Abram, he had no children, no land, and no clear understanding of how God’s promises would come to pass. 

But something changed. 

In Genesis 15, God made a covenant with Abram, revealing His plans and binding Himself to the promises He had made. Later, in Genesis 17, God changed his name from Abram (“exalted father”) to Abraham, meaning “father of many nations”—before he had any children! This name change was an act of faith, a step into covenant identity. 

The apostle Paul explains this transformation in Romans 4:20–21 (KJV): “He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God; And being fully persuaded that, what he had promised, he was able also to perform.” 

Abraham became fully persuaded—not because his circumstances changed, but because he understood God’s covenant nature. 

David and Jonathan: A Covenant of Loyalty 

In 1 Samuel 18:3–4, we see a beautiful picture of covenant between David and Jonathan. Jonathan, the king’s son, made a covenant with David and gave him his robe, armor, sword, and bow—symbols of identity, strength, and loyalty. In their culture, this meant, “My life is bound with yours, even unto death.” 

Years later, after Jonathan had died and David became king, David remembered the covenant. Despite Mephibosheth’s disability and the potential political threat he posed as Saul’s descendant, David honored the covenant. 

In 2 Samuel 9, David said, "Is there yet any that is left of the house of Saul, that I may shew him kindness for Jonathan’s sake?" (KJV) 

He welcomed Mephibosheth to his table—not because of who Mephibosheth was, but because of the covenant. In the same way, God welcomes us because of the covenant He has with His Son, Jesus. 

Jesus Christ: The New Covenant Sealed in Blood 

God always had a plan for a new covenant—a better one. In Jeremiah 31:31–33 (KJV), God promised: “Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel... I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.” 

Jesus fulfilled that promise. 

At the Last Supper, Jesus said in Luke 22:20 (KJV): “This cup is the new testament in my blood, which is shed for you.” 

He was sealing a new covenant—the blood covenant in Christ—not just for Israel, but for all who believe. His sacrifice was once and for all, eternally binding. 

As the writer of Hebrews declares: “But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.” (Hebrews 8:6, KJV) 

This covenant isn’t based on our goodness. It’s based on Jesus’ finished work on the cross. It’s not sealed with animal blood or human promises, but with the precious blood of the Son of God. 

What This Covenant Means for You 

When you understand your blood covenant in Christ, everything changes. 

You realize you’re not just forgiven—you’re adopted (Romans 8:15). You’re not just saved—you’re seated in heavenly places (Ephesians 2:6). You’re not alone—you’re in covenant with the living God, and He cannot break His Word. 

Just like Abraham, your faith can grow strong when you become convinced of the One who made the promise. 

Galatians 3:29 (KJV) tells us: “And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise.” 

You are an heir—not of some old, distant story—but of a living, present blood covenant in Christ. The more you study and understand what’s been promised to you, the more your faith will grow. 

Living in Covenant Identity 

The key to walking in victory is understanding who you are and what belongs to you through the covenant. Just as Abraham began to walk differently after receiving his covenant identity, we too are called to live boldly, pray confidently, and trust unwaveringly in our covenant-keeping God. 

Spend time in the Word. Let the Holy Spirit reveal the depth of what Jesus has done for you. When you truly grasp it, fear fades, doubt dissolves, and faith takes root.
