Salvation, Eschatology and the Problem of Evil
Salvation and the Role of Christ
Christian teaching about salvation is built on four connected ideas: law, sin, grace and Spirit. The law of the Old Testament sets out God’s standard for human behaviour. Sin is the human failure to meet that standard, which breaks the relationship between people and God. Grace is God’s free, undeserved gift of forgiveness, made possible through Jesus Christ. The Holy Spirit then applies this salvation to individual believers, assuring them of God’s love and helping them live a holy life.
The Gospel of John shows how central belief is to salvation. In John 3:10–21, Jesus tells Nicodemus, “For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life” (John 3:16). This passage teaches that salvation comes through believing in Jesus as the Son of God.
The role of Christ in salvation is stated directly in Acts 4:8–12, where Peter tells the religious leaders in Jerusalem, “Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved.” For Christians, this means Jesus is not one way to God among many, but the way salvation becomes possible.
Christian salvation rests on four linked ideas: law reveals God’s standard, sin is human failure to meet it, grace is God’s free forgiveness through Christ, and the Spirit applies this salvation to believers. John 3:10–21 and Acts 4:8–12 both teach that salvation comes only through Jesus Christ.
Atonement means making amends for wrongdoing. In Christianity, it describes how Jesus’s death deals with the effects of sin and restores the relationship between humanity and God. Atonement and salvation are closely linked: it is through the atoning death of Christ that salvation becomes possible. Without the atonement, Christians believe, sin would remain an unbridgeable barrier between people and God.
Christian Eschatology: Life After Death
Eschatology is Christian teaching about “last things”. Most Christians believe that after death, the dead will be resurrected and will face God’s judgement. Those judged favourably enter heaven, an eternal state of joy in God’s presence; hell is understood as eternal separation from God. Christians hold divergent views on exactly how judgement, heaven and hell work, but resurrection and judgement are shared beliefs across almost all traditions.
2 Corinthians 5:1–10 is an important source for these teachings. Paul writes that believers who die will receive “a building from God, an eternal house in heaven” (2 Corinthians 5:1), and warns that “we must all appear before the judgment seat of Christ, so that each of us may receive what is due us for the things done while in the body” (2 Corinthians 5:10). This passage teaches both resurrection into a new heavenly body and accountability at judgement.
Catholic teaching adds a further belief: purgatory, a period of purification for souls who die in God’s grace but are not yet perfectly holy. This is not a second chance for the unrepentant, but preparation for those already destined for heaven.
Many other Christians, however, reject purgatory. The 39 Articles of Religion state that the Catholic teaching on purgatory “is a fond thing vainly invented, and grounded upon no warranty of Scripture.” Christians are also divided about the exact nature of hell: some understand it as eternal conscious punishment, others as the final ending of the unrepentant, and others hope God will ultimately reconcile all people to himself. These divergent views matter today because they shape how urgently Christians feel called to share their faith, and how they understand God’s justice and mercy.
The 39 Articles reject purgatory as unbiblical, while Catholic teaching affirms it as a process of purification before heaven. Christians agree on resurrection and judgement but hold divergent views on the exact nature of hell and purgatory.
The Problem of Evil and Suffering
If God is omnipotent and benevolent, why does evil and suffering exist? This question is known as the problem of evil. If God can prevent suffering and truly loves his creation, it seems he should stop it — yet suffering continues. This tension can cause believers to question their faith, or even whether God exists at all.
Christians distinguish two kinds of suffering. Moral suffering is caused by human choices, such as war, cruelty or theft. Natural suffering is caused by events in the natural world, such as earthquakes, floods or disease. Moral suffering raises questions about why God allows humans to misuse their freedom; natural suffering raises questions about why a good God would design a world that causes suffering independently of human choice.
Psalm 103 offers one biblical response. It declares, “The Lord is compassionate and gracious, slow to anger, abounding in love” (Psalm 103:8). Christians use this verse to argue that God’s love for those who suffer is itself part of the answer — God does not stand distant from suffering but responds to it with compassion.
The problem of evil challenges belief in God because an all-powerful, all-loving God appears able and willing to stop suffering, yet suffering continues. Christians distinguish moral suffering (caused by human choice) from natural suffering (caused by natural events).
Divergent Solutions to the Problem of Evil
Psalm 119 responds to suffering by trusting God’s purpose within it: “It was good for me to be afflicted so that I might learn your decrees” (Psalm 119:71). This suggests suffering can have spiritual value, teaching believers obedience and dependence on God.
The book of Job explores the problem at length. Job, a righteous man, loses his family, health and wealth without having done anything to deserve it. He protests directly to God, but God does not explain why Job suffered. Instead, God reveals his own greatness, and Job responds, “My ears had heard of you but now my eyes have seen you” (Job 42:5). Job’s story suggests Christians may not receive an explanation for suffering, but can still trust God through an encounter with him.
Christians also offer theoretical solutions. The free will defence argues that God gave humans genuine freedom, and moral suffering is the result of humans misusing that freedom rather than God’s fault. Critics argue this defence explains moral suffering but not natural suffering, which is not caused by human choice at all, questioning how successful it really is.
Another theoretical solution is known as the vale of soul-making. This solution suggests the world was never meant to be free of suffering; instead, suffering and challenge are the conditions through which humans grow morally and spiritually. Critics argue it is hard to see how extreme or undeserved suffering, such as that endured by children, could ever serve a person’s soul-making.
Christians also respond to suffering practically, through prayer and charity. Prayer allows believers to bring their own suffering, and the suffering of others, to God, seeking comfort and strength. Charity puts faith into action: Christians support those who suffer through practical acts of care, seeing this as a direct response to Jesus’s example and teaching.
Christians respond to the problem of evil in three ways: biblical (Psalm 119, Job), theoretical (free will defence, the vale of soul-making) and practical (prayer, charity). None fully removes the problem, but together they shape how Christians live with suffering.
