How does spiritual life come according to Reformed theology?

According to Reformed theology, spiritual life is not something that humans can achieve through their own actions or decisions; rather, it is a gift from God. Jesus said, 'For as the Father hath life in himself, so hath He given to the Son to have life in himself' (John 5:26). Spiritual rebirth is a work of the Holy Spirit, who awakens a person's heart to respond to the gospel. This underscores the doctrines of grace, which emphasize that salvation and the ability to respond to God are entirely the result of divine initiative. Just as Lazarus had no ability to resurrect himself, we have no capacity to attain spiritual life apart from God’s sovereign grace.
