Storing up treasures in heaven means prioritizing our relationship with Jesus and focusing on heavenly pursuits rather than material wealth (Matthew 6:19–21; Colossians 3:2–4). It involves making Jesus our primary treasure, offering our time, talents, and resources to honor Him (1 Corinthians 10:31). Every act done in His name, including enduring persecution, contributes to our heavenly reward (Matthew 10:42; 2 Timothy 3:12). The Bible assures that the sacrifices made for the gospel are not in vain (Romans 8:18; 1 Corinthians 15:58). It also speaks of rewards and crowns awaiting believers (Matthew 10:41; 1 Corinthians 3:12–15; 2 Timothy 4:6–8). By living for Christ and His kingdom, we store up treasures that are eternal (Colossians 3:23–24) instead of living for what is temporary.
Storing up treasures in heaven does not mean that we cannot have earthly treasures, but we should consider them of far less value than the treasure that is Christ and Him crucified for our sins (1 Corinthians 2:2). The rich young ruler was a man who believed he had kept God's commandments throughout his life. He came to Jesus to find out how he could have eternal life: "Jesus said to him, 'If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me.' When the young man heard this he went away sorrowful, for he had great possessions" (Matthew 19:21–22). This story demonstrates that no matter how "good" we think we are, it is our heart posture toward God that matters most. When He is truly our greatest treasure, we are willing to give everything we have for the sake of Christ—even to the point of persecution and death.
