What does the Bible say about God's visitation in believers' lives?

In Genesis 21:1, it is noted that 'the Lord visited Sarah as he had said.' This visitation signifies God's active presence in the lives of believers, granting them grace and enabling them to experience spiritual birth and growth. Just as God visited Sarah and fulfilled His promise to give her a son, He similarly visits every believer, imparting spiritual life and transformation. The visitation of God is a reminder that salvation is entirely a work of grace, where individuals cannot generate spiritual life on their own but rely solely on God's initiative.
