When something drops into your life that seems to threaten your future, remember this: the first shockwaves of the bomb are not sin. The real danger is yielding to them. Giving in. Putting up no spiritual fight. And the root of that surrender is unbelief - a failure to fight for faith in future grace. A failure to cherish all that God promises to be for us in Jesus.
