Salvation results from believing in the Lord Jesus Christ - Period (Acts 16:31; Eph. 2:8; etc.)! Jew, Gentile, whosoever, if he will place his trust in the One Who died for his sin, Who was buried, and Who rose again from the grave, all according to the Scriptures (1 Cor. 15:3-4), he shall, shalt, in other words, will be saved. All those who truly believe and trust in the Lord Jesus, will be sealed by the Holy Spirit (2 Cor. 1:22; Eph. 1:13; 4:30), and as a result, will endure whatever the world and its god, Satan, can throw at them (Jn. 17:14; 1 Jn. 3:13; 2 Cor. 4:4)! Praise God! Here is but a taste of what God's Word says on the subject:
