In John 15, Jesus compares the believer’s relationship with God to a branch that receives life from a vine, a fitting metaphor of how personal change takes place, revealing how the concepts of theology, identity, and transformation are inextricably linked.
What we discover in Jesus' analogy is that change does not take place through greater willpower, determination, promises, and human resolve. Change is the result of a vital union whereby a believer abides in Jesus by faith as his or her sin-bearer, righteousness provider, Sustainer, and Sanctifier.
As we abide in the justifying grace of Jesus we receive the sanctifying grace of the Holy Spirit, who gives us new desires and new abilities to produce good fruit. This good fruit is the result of the Spirit’s work in the life of the believer. As we say, the fruit depends on the root.
Therefore, faith-union with Christ as one’s Justifier and Sanctifier is the key to change and provides the theological foundation and spiritual fuel for all the resources available through mckaycaston.com.
This is why our mission is to help Christians experience the wonder, beauty, and transforming power of the gospel. When we come alive to the wonder of God's mercy and grace, everything changes. How I view God and myself. How I engage with the world. How I treat my wife and kids. How I face loss, defeat, and suffering. How I deal with victory and success. Yes, grace changes everything.
If justification is our initial union with Jesus (which takes place through faith), sanctification is our ongoing union with Jesus (which takes place by the same faith through which a sinner is justified).
