Why is it important for Christians to understand the concept of God's calling?

The concept of God's calling is essential because it illustrates that salvation does not begin with our decision but with His initiative. Just as Boaz called Ruth, God calls us to Himself, showing us that it is His grace that draws us to repentance and faith. This truth is illustrated in 1 Peter 5:7, where we are reminded to cast our cares upon Him because He cares for us. Realizing that we love Him because He first loved us (1 John 4:19) underscores the affection with which God reaches out to us and the importance of His calling.
