Definition and Concept:
Eternal impact refers to the lasting effect of one's actions, decisions, and life on the eternal realm, as understood within Christian theology. It encompasses the idea that what individuals do in their earthly lives can have consequences that extend beyond temporal existence and into eternity. This concept is rooted in the belief that life on earth is a preparation for eternal life, and that one's faith, works, and obedience to God can influence their eternal destiny and the destinies of others.

Biblical Foundations:
The Bible provides numerous references that underscore the significance of living with an eternal perspective. In Matthew 6:19-20 , Jesus instructs, "Do not store up for yourselves treasures on earth, where moth and rust destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where moth and rust do not destroy, and where thieves do not break in and steal." This passage highlights the importance of prioritizing eternal values over temporal gains.

The Apostle Paul also emphasizes eternal impact in 2 Corinthians 4:17-18 : "For our light and momentary affliction is producing for us an eternal glory that is far beyond comparison. So we fix our eyes not on what is seen, but on what is unseen. For what is seen is temporary, but what is unseen is eternal." Here, Paul encourages believers to focus on the unseen, eternal realities rather than the temporary struggles of this world.

Eternal Impact through Faith and Works:
The relationship between faith and works is central to understanding eternal impact. James 2:26 states, "As the body without the spirit is dead, so faith without deeds is dead." This indicates that genuine faith is demonstrated through actions that have eternal significance. Believers are called to live out their faith in ways that reflect God's love and truth, thereby impacting the world for eternity.

In Matthew 25:31-46 , the Parable of the Sheep and the Goats illustrates how acts of kindness and service to others are seen as service to Christ Himself, with eternal consequences. Jesus concludes, "Truly I tell you, whatever you did for one of the least of these brothers of Mine, you did for Me" (Matthew 25:40). This parable underscores the eternal impact of compassionate actions.

The Role of Evangelism and Discipleship:
Evangelism and discipleship are key components of making an eternal impact. The Great Commission in Matthew 28:19-20 commands believers to "go and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, and teaching them to obey all that I have commanded you." By sharing the Gospel and nurturing new believers, Christians contribute to the eternal destinies of others.

Eternal Rewards and Accountability:
Scripture teaches that believers will be rewarded for their faithfulness and service. In 1 Corinthians 3:12-15 , Paul describes how each person's work will be tested by fire, and those whose work endures will receive a reward. This passage highlights the eternal impact of building one's life on the foundation of Christ with materials that withstand divine scrutiny.

Furthermore, Romans 14:10-12 reminds believers of their accountability before God: "For we will all stand before God’s judgment seat... So then, each of us will give an account of himself to God." This accountability underscores the importance of living with an awareness of the eternal consequences of one's actions.

Conclusion:
The concept of eternal impact is woven throughout the biblical narrative, calling believers to live with an eternal perspective. By prioritizing faith, works, evangelism, and discipleship, Christians are encouraged to make choices that resonate in eternity, aligning their lives with God's eternal purposes.
