This is a sample chapter from my Systematic Theology project "Theology for Thriving". 📎MORE TO THE STORY notes are not part of the main text of the book, but additional resources, charts, or other materials from Biblical Theology class resources.
Hebrews 11.1-3, 6-10 [1] Now faith is the assurance of things hoped for, the conviction of things not seen. [2] Indeed, by faith our ancestors received approval. [3] By faith we understand that the worlds were prepared by the word of God, so that what is seen was made from things that are not visible... [6] And without faith it is impossible to please God, for whoever would approach him must believe that he exists and that he rewards those who seek him. [7] By faith Noah, warned by God about events as yet unseen, respected the warning and built an ark to save his household; by this he condemned the world and became an heir to the righteousness that is in accordance with faith. [8] By faith Abraham obeyed when he was called to set out for a place that he was to receive as an inheritance; and he set out, not knowing where he was going. [9] By faith he stayed for a time in the land he had been promised, as in a foreign land, living in tents, as did Isaac and Jacob, who were heirs with him of the same promise. [10] For he looked forward to the city that has foundations, whose architect and builder is God.
🗝️ Key Concept: Faith(fulness)
If Theosis is the ultimate destination on our spiritual map— the journey of participating in God’s own life— then how do we take the first step? How do we actively receive the grace that makes this journey possible? The answer is found in our key concept: Faith(fulness).
In our modern world, "faith" has often been reduced to a purely intellectual exercise. For many, it simply means believing a list of correct ideas about God, an assent to a set of facts. While what we believe certainly matters, this definition is a pale shadow of the rich, dynamic, and life-altering reality the Bible describes. To grasp the biblical concept, we have to see faith not just as a noun, but as a verb; not just as a belief, but as a way of being.
The Old Testament builds its understanding of faith on God’s own character. The Hebrew words for faith, emet and emunah, are rooted in the idea of firmness, reliability, and trustworthiness. Before the people of Israel are ever asked to have faith in God, the story first demonstrates that God is faithful to them. The LORD is the one who keeps promises, who shows steadfast love to a stubborn and unfaithful people. The prophets’ primary job was to call Israel back to a life of faithfulness that mirrored God’s own. The great hero Abraham is the prime example. His “faith” was counted as righteousness not because he passed a theology exam, but because his inner trust in God issued forth in the outward action of leaving his home and journeying into an unknown future, guided only by God’s promise.
The New Testament builds on this foundation. The Greek word for faith, pistis, carries this same dual meaning of trust and loyalty. Following the work of scholars like N.T. Wright, we can see that the gospel is not primarily about our faith in Jesus, but about the faithfulness of Jesus Christ. Jesus is the embodiment of God’s own covenant faithfulness, the perfectly loyal Israelite who succeeds where all others failed. It is His faithfulness that saves us and restores our broken relationship with God. Our response, then, is to participate in His faithfulness with our own.
This is why the key concept for this chapter is the dual word "faith(fulness)": Because Jesus' faithfulness calls us to not only have faith in him, but practice faithfulness to him. This rich, biblical faith(fulness) has at least three interconnected dimensions:
Cognitive: It includes our beliefs, the "what" of our faith. It is the intellectual assent to the good news that God, in Christ, has acted to save the world.
Affective: It involves our hearts, the "who" of our faith. It is a radical trust in God’s goodness, a confident reliance on His presence and providential care in our lives.
Volitional: It engages our will, the "how" of our faith. It is active loyalty, an obedient journeying with God as we seek to co-write our chapter of His redemptive story.
