Sure, the kids will appreciate the inheritance, but they will appreciate even more the idea that you are enjoying what God has given you and, if you feel so moved, being generous with it now. Take your children and grandchildren out to Saturday lunch. Give the money to your church, or to Anglicare or to CMS or AFES. Die broke but happy! For "Look at the birds of the air: they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than they?"
Not to mention.
So spend it now, thank God, and enjoy it!
