Francis Schaeffer used to say - I am casting stones into a pond and making ripples that go on forever...
I think about [my family] - every moment I spend with them, which is precious, God assures me that is going to be raised-up in the kingdom to come.
Everything that is worthwhile now will endure forever.
Every meal we serve to somebody - Jesus says every cup of cold water I give to somebody - every kind word, every act of service is going to last forever; it's going to be of eternal significance in other people's lives.
From Jerram Barrs
That is the Christian promise. Could anything better be imagined? Not by me.
