I believe a man may be as vile as hell itself one moment and be saved the next. - D.L. Moody
Ephesians 4:30, And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
Not only does the Spirit indwell the saved man, He also seals the saved man until the day of redemption. We are eternally secure in Jesus because the Spirit dwells within us. This security brings about a confidence in Jesus Christ. It gives us a boldness to be a witness for Him. Many Christians struggle with being a witness because they do not have the assurance of their salvation. Many don’t have that assurance because they neglect their personal Bible reading. Vanhetloo states, “If we believe that this is the message of God for us, we will read this message.” It is imperative for us to have that assurance and we will get it when we get into the Scriptures.
