Question:
If a person is saved, but not walking in Christ, if he dies will he go to heaven?

Answer:
Ephesians 2:8 says that salvation is a “gift of God,” and God does not take His gifts back (Romans 11:29).

Saved from what?—Saved from perishing (John 3:16, 17). Saved from wrath (Romans 5:9).
It is possible to live for Christ. “For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death” (Romans 8:2). If we are “born again,” we can’t be unborn. He will treat us as His children, train and discipline us. He calls us: “My son” (Hebrews 12:5), and a perfect Father (God) won’t kick His son out of His family.
