I believe that each one of us wants to make our mark in this life, to leave a legacy of some kind. This desire is often fulfilled by writing a book, fashioning a sculpture, painting a picture, building a structure, or instructing the next generation.
While all these things are good and fulfilling, only what is done in Christ is of any real eternal value. Like the rain that falls on the earth, the fruit of it only lasts a season and then it withers and dies.
God’s offer of salvation in Christ Jesus is only offered and available in this brief time period we call life. The saved are eternally saved and the lost are eternally lost. There is no reversal of choice.
Choose you this day whom you will serve. God sets before you death and life and desires that you choose life.
