The wide-open fields of the Enemy are not wide and free as we might think. They are a maze of constantly changing “right and wrong”. Our footsteps are never sure or confident when there are no absolute standards! Living in relativism causes confusion, insecurity, and fear (Isaiah 33:15; Romans 7:11; Psalm 36).
However, the walls of God’s Kingdom are widely-set, so spacious in fact that we have room to run and dance, and space to fall and make mistakes. We feel secure inside His protective barriers, inside His grace-space.
Instead of the simplicity of grace, Pharisees dressed in layers of law-keeping and the high-fashion of religiosity. It could not have been comfortable. There was never any wiggle room for somebody to make a mistake, to struggle, to fall. Jesus condemned their rigid judgmental attitudes. “The Law and the Prophets were until John. Since that time the kingdom of God has been preached, and everyone is pressing into it” (Luke 16:16, emphasis mine). His grace extended to tax-collectors, prostitutes, and indeed everyone that recognized their need.
There's a Wideness in God's Mercy
