What does the Bible say about God's effectual call?

The Bible speaks of God's effectual call in various ways, demonstrating that while the general call to salvation goes out to all through the preaching of the gospel, it is only when the Holy Spirit works in an individual's heart that true transformation occurs. In verses like Romans 8:30, we see that those whom God predestines are called, justified, and glorified. This highlights the sovereignty of God in the salvation process, emphasizing that salvation is a divine work from start to finish, wherein God qualifies us to partake in the inheritance of the saints (Colossians 1:12). Ruth's journey alongside Naomi is emblematic of this effectual calling, as she was drawn away from her previous life into a new relationship with the God of Israel by His grace.
