Jesus tells His followers they must pick up their cross and follow Him (Luke 9:23). A cross is not a symbol of trying harder, of promising to do better, of really knuckling down, getting serious, and having "the eye of the tiger."
A cross is not where you go to work out, as if to build up what is already there.
A cross is where you go to die, which is the final negation of the sin-riddled nature we inherit from Adam. ~ Excerpt from The World Tilting Gospel by Dan Phillips
Let us follow wherever He leads.
