The movement of the trees as Jonathan passes is a reminder of how "creation waits in eager expectation for the sons of God to be revealed." (Romans 8:19) Perhaps the branches were clapping! Trees have a place in heaven. The fruitful tree of life from the Garden of Eden is described prominently in the book of the Revelation.
Our little boy had run races on the school playground. The Christian life is like a race. For instance, the apostle Paul says he "finished the race" and "kept the faith." (2 Timothy 4:7) Eric Liddell, the main character fromt the movie CHARIOTS OF FIRE, said "God made me fast. And when I run I feel His pleasure." Jonathan probably shared a similar feeling.
An eagle was flying near his car. This type of bird signals judgment on the earth at the end of time. (Revelation 8:13) Also, those who hope in the Lord can "soar on wings like eagles." (Isaiah 40:31)
A great river is described as part of heaven. This "river of the water of life, as clear as crystal, flowing from the throne of God" is in the middle of the New Jerusalem. (Revelation 22:1)
Heaven will be beyond anything we expect but it will not be totally unfamiliar. Jonathan sees his sister and his house. We are told that people, places and activities in heaven have their origin on this earth. But the next life will offer perfection which we have never experienced.
Just like Jonathan wanted Rachel to be with him, we too are called to lead others to heaven. They were thrilled about the day that awaited them. "Rejoice and be glad because great is your reward in heaven." (Matthew 5:12)
Rachel was obviously very curious about the car. There is every indication that our curiosity and learning will not end in this life. (Revelation 6:10; 1 Corinthians 13:12) "What would she check out first?" She had decisions to make. We will have responsibilities in heaven and make decisions too. (Matthew 25:21)
