In Luke 23:43, Jesus declared, "Truly I say to you, today you shall be with me in paradise." The word Jesus used for "paradise" is paradeisos which means "a park, that is, (specifically) an Eden (place of future happiness, paradise)". Paradeisos is the Greek word taken from the Hebrew word pardes which means "a park: - forest, orchard" (Strong’s). Jesus said, "Today you shall be with me "en paradeisos," not "en nephele" which is Greek for “in clouds.” The point is that Jesus picked and used the word for "a park." Not just any park but "the paradise of God" or park of God (Revelation 2:7) which for us will be a place of future happiness. Does this sound like a boring place? When you think of a park, do you think of boredom?
Jesus said, "You shall worship the Lord your God, and Him only you shall serve" (Matthew 4:10). It’s interesting to note that Jesus did not say "praise and serve." Even the briefest examination of the word praise in the Bible quickly shows it’s a verbal thing and is for the most part singing. Worship, however, is from the heart. Worship manifests itself in praise. Serving God is worship, and Scripture is clear we will serve God in heaven. "His servants will serve Him" (Revelation 22:3).
We are unable to fully serve God in this life due to sin, but in heaven "every curse will no longer be" (Revelation 22:3). We will not be under the curse of sin any longer, so everything we do will be worship in heaven. We will never be motivated by anything other than our love for God. Everything we do will be out of our love for God, untainted by our sin nature.
So what will we do? My favorite thing is to learn. "For who has known the mind of the Lord, or who became His counselor?" (Romans 11:34), "in whom are hidden all the treasures of wisdom and knowledge" (Colossians 2:3). God is the "the high and lofty One who inhabits eternity" (Isaiah 57:15). God is bigger than forever, and it will take eternity "to comprehend with all saints what is the breadth and length and depth and height, and to know the love of Christ" (Ephesians 3:18-19). In other words, we will never stop learning.
God’s Word says we won’t have to be in His paradise alone. "I shall fully know even as I also am fully known" (1 Corinthians 13:12). This would seem to indicate that we will not only know our friends and family, we will "fully know" them. In other words, there is no need for secrets in heaven. There is nothing to be ashamed of. There is nothing to hide. We will have eternity to interact with "a great multitude, which no man could number, out of all nations and kindreds and people and tongues" (Revelation 7:9). No wonder heaven will be a place of infinite learning. Just getting to know everyone will take eternity!
Any further anticipation about what we shall do in God’s eternal park, heaven, will be far surpassed when "the King shall say to those on His right hand, 'Come, blessed of My Father, inherit the kingdom prepared for you from the foundation of the world'" (Matthew 25:34). Whatever we will be doing, we can be sure it will be wonderful beyond our imaginations!
