Does God give his grace only to Christians? (Q138)
From To Be A Christian, An Anglican Catechism
No. God graciously provides for all people; “he makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust” (Matthew 5:45). However, he shows his saving grace by bringing to faith in Christ those who are far from him. (Romans 5:1-11).
