What does a holy calling mean in Christianity?

In Christian doctrine, particularly within Reformed theology, a 'holy calling' refers to the divine purpose by which God saves His people, as articulated in 2 Timothy 1:9. This calling is outlined as not according to our works, but according to His own purpose and grace, indicating that this divine initiative precedes any human action. Believers are called to participate in the life of Christ, which includes being transformed and sanctified for divine purposes. This reinforces the idea that salvation is entirely of God’s design, rooted in His covenantal love and promise, as demonstrated before the foundation of the world.
