Life’s race is not sprint, but marathon!
Sprint describes quickness while marathon expresses continuity and sustenance.
In sprint you make effort but by marathon you show determination.
Endurance is the real test of a good soldier.
It is the ability to withstand all situations and wheather all storms of life. II Tim.2:3-5
It’s foundation is discipline that is, putting yourself under constrain and compulsion in pursuit of life endeavors. 1 Cor.9:24-26;
Joy is the fountain of endurance. Heb.12:2
