Jesus is the only Hope of assurance!
The Bible offers the only hope and assurance that really matters. It is the kind of hope that neither the Qur’an nor Muhammad in his traditions offer. It is the hope of eternal life. In reference to Jesus as the Christ, the Bible declares, “God has given us eternal life, and this life is in his Son” (1 John 5:11). Jesus is the only way. “Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved” (Acts 4:12).
Those who embrace Jesus, accepting him as the only way, find in Him full salvation and the assurance of eternity in heaven. This is the promise God made, accounted in the Bible: “As many as received Him, to them He gave the right to become children of God, to those who believe in His name” (John 1:12). This promise is further explained that if we are children of God “then we are heirs - heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory” (Romans 8:17).
The Bible declares, “it is appointed for men to die once, but after this the judgment” (Hebrews 9:27). We cannot save ourselves or please God through our own efforts or intelligence. We can come to him through Jesus, admitting our weakness that indeed, “there is none righteous, no, not one … for all have sinned and fall short of the glory of God” (Romans 3:10, 23). Jesus said, “I tell you, no; but unless you repent you will all likewise perish” (Luke 13:3, 5).
When we recognize that by our own efforts we cannot save ourselves and come to him in repentance, God offers salvation to us through Jesus. He bore the full penalty of sin on behalf of all who would trust him (Isaiah 53:4-6; 1 Peter 3:18; 1 Corinthians 15:3). This salvation is offered freely to all who believe in him (Revelation 22:17; Matthew 11:28-30; John 3:16, 18; John 5:24; Romans 10:9).
Please do not make the mistake of those who, “being ignorant of God’s righteousness, and seeking to establish their own righteousness, have not submitted to the righteousness of God” (Romans 10:3). Indeed the Qur’an talks about God’s love, his forgiveness, and mercy, but all these aspects are bound with conditions upon human beings, their obedience, and the way they respond to God’s guidance. In spite of all efforts, the follower is still not sure of his destiny.
Both the Qur’an and the Bible talk about the sinful state of humans on this earth. It is the Bible only that speaks further concerning this issue and gives guidance to being saved from sin by God. First of all, it teaches that all our efforts to find God through laborious moral attempts will come to nothing. Our inside (spirit, soul) has to be changed; a reshaping from within has to take place.
