Definition:
Eternal investments refer to the spiritual and moral actions, decisions, and priorities that align with God's will and have everlasting significance. These investments are contrasted with temporal, earthly pursuits that are transient and ultimately perishable.

Biblical Foundation:
The concept of eternal investments is deeply rooted in Scripture, where believers are encouraged to prioritize heavenly treasures over earthly ones. Jesus Christ, in His teachings, emphasized the importance of focusing on what is eternal. In the Sermon on the Mount, He instructed, "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. For where your treasure is, there your heart will be also" (Matthew 6:19-21).

Principles of Eternal Investments:

1. Heavenly Treasures:
Believers are called to invest in heavenly treasures, which include acts of love, mercy, justice, and faithfulness. These are actions that reflect God's character and have eternal value. The Apostle Paul writes, "Set your minds on things above, not on earthly things" (Colossians 3:2), urging Christians to focus on the eternal rather than the temporal.

2. Stewardship:
The Bible teaches that everything a believer possesses is entrusted to them by God, and they are to be faithful stewards of these resources. Jesus' Parable of the Talents (Matthew 25:14-30) illustrates the importance of using one's gifts and resources for God's kingdom, highlighting that faithful stewardship will be rewarded in eternity.

3. Generosity and Sacrifice:
Acts of generosity and self-sacrifice are seen as investments in eternity. Jesus commended the widow who gave all she had (Mark 12:41-44), and Paul encouraged the Corinthian church to give generously, stating, "Each one should give what he has decided in his heart to give, not out of regret or compulsion. For God loves a cheerful giver" (2 Corinthians 9:7).

4. Evangelism and Discipleship:
Sharing the Gospel and making disciples are considered significant eternal investments. Jesus' Great Commission (Matthew 28:19-20) commands believers to spread the message of salvation, which has eternal implications for those who receive it.

5. Righteous Living:
Living a life that reflects God's righteousness is an investment in eternity. The Apostle Peter exhorts believers to live holy and godly lives, "as you anticipate and hasten the coming of the day of God" (2 Peter 3:11-12).

Eternal Rewards:
The Bible speaks of rewards for those who make eternal investments. In 1 Corinthians 3:12-14, Paul describes how each person's work will be tested by fire, and those whose work endures will receive a reward. Jesus also promises rewards to those who are faithful, saying, "Behold, I am coming soon, and My reward is with Me, to give to each one according to what he has done" (Revelation 22:12).

Conclusion:
Eternal investments are a central theme in the Christian life, encouraging believers to focus on actions and decisions that have lasting significance in God's kingdom. By prioritizing heavenly treasures, practicing faithful stewardship, and living righteously, Christians align themselves with God's eternal purposes.
