There are people in my life that caught a vision of what I might be, and spent themselves in seeing it come to pass. Ancestors long gone that prayed for future generations to know Jesus and serve Him, and Christ himself, who, "for the joy set before him endured the cross, scorning its shame, and sat down at the right hand of the throne of God". (Hebrews 12:2)
Christ's joy was the redemption of God's creation, the restoration of fellowship for God's children whom He made in His image.
I look forward to that day when I will be able to thank those in person to whom I owe my spiritual inheritance, especially my Redeemer. But for now, I want to be a tree of righteousness, "the planting of the LORD, that he might be glorified." (Isaiah 61:3) And I want to have a vision for my children, grandchildren, and great granchildren, spending myself in prayer that they might know their spiritual inheritance.
