Understanding Unbelievers: A Biblical Perspective on Faith, Evangelism, and Eternal Destiny

The Condition and Destiny of Those Outside of Christ

God desires that none should perish but that all come to repentance (2 Pet 3:9). Yet Scripture is clear that those who die without knowing Christ as Saviour face eternal separation from God. Though they may possess a knowledge of God’s existence, they lack a saving relationship with Him (Rom 3:18). Jesus warned that on the day of judgment, many will say, “Lord, Lord,” but He will declare, “I never knew you” (Mt 7:23). The fate of the unrighteous is described as eternal fire and outer darkness (Mt 13:49,50, 25:11,12; Lk 12:46, 13:24–27). While they may live morally upright lives, good works apart from faith cannot reconcile them to God (Eph 2:8,9). Without Christ, they remain under condemnation and face the second death (Jn 3:17,36; Rev 20:15, 21:8).

Engaging the Unbelieving World with Grace and Truth

Just as Jesus was known as “the friend of sinners” (Mt 11:19; Lk 7:34), believers are called to be salt and light in the world (Mt 5:13–16). Through intentional relationships, good works, and faithful witness, we are to sow seeds of the gospel (Mt 28:18–20;

Gal 6:10). Friendship evangelism allows us to understand an unbeliever’s worldview and to give “a reason for the hope that is within us” with gentleness and respect ( Act 17:16–34; 1 Pet 3:15). However, Scripture also warns against close association with those who promote gross immorality or actively oppose the faith, as “bad company corrupts good morals” (1 Cor 15:33; Eph 5:7,12; 2 Cor 6:14–17). The godless are blinded by Satan (2 Cor 4:4). Persistent rejection of truth can lead to divine confirmation of their hardened hearts (Jn 12:40,41).

Though believers are not to be unequally yoked in marriage or business with unbelievers (2 Cor 6:14–17), we are called to coexist peaceably and serve as witnesses in everyday life (Mt 5:13–16). In some cases, a believing spouse’s consistent godly life may lead the other to faith (1 Cor 7:14,15). While the message of salvation remains unchanging — Christ alone is the way, the truth, and the life — the methods of sharing it must be culturally relevant and accessible (Jn 14:6; Act 4:12). The gospel must be communicated clearly, invitingly, and in a language others can understand.

What about those who have never heard? Scripture affirms that God has revealed Himself through creation and the human conscience (Ps 19:1; Rom 1:20; Eccl 3:11). All are accountable for the light they have received, and many suppress the truth in

unrighteousness, exchanging the glory of God for idols (Ex 20:3–6; Hab 2:18; Rom 1:18–23). Rather than speculating on the eternal destiny of the unevangelized, believers are commissioned to go and make disciples of all nations (Mt 28:19,20; Act 1:8).

Regarding those who cannot believe — such as unborn children, infants, or the severely mentally disabled — the Bible does not explicitly state God’s provision. Yet we trust in the character of God, who is just, merciful, and gracious. “Shall not the Judge of all the earth do right?” (Gen 18:25).

Reflection and Application:

Consider how your daily interactions reflect Christ’s love for unbelievers — are you actively being salt and light in your sphere of influence?
Reflect on whether you are relying on the Holy Spirit for boldness and wisdom when sharing your faith, especially in challenging conversations.
Ask yourself if you are investing in relationships with non-believers, not just for evangelism, but out of genuine care and friendship.
Commit to growing in your understanding of different worldviews, so you can communicate the unchanging gospel in culturally relevant ways.
