How do we know that God's calling is a holy calling?

In 2 Timothy 1:9, Paul clarifies that God has called us with a holy calling, not according to our works, but according to His own purpose and grace. This holy calling underscores that God’s plans were established before the foundation of the world, highlighting His sovereign will and divine initiative. It ensures that every believer has been set apart for His purposes – to live a life of holiness and righteousness. As we reflect on our calling, we should marvel at how God, in His grace, chose us and equipped us to fulfill His mission, prompting gratitude and reverence in our hearts.
