We’re constantly making choices, moment by moment, in a continuous flow of sowing and reaping. A universal law governs this: whatever we sow, we reap. (Ga 6:7b) If we invest primarily in our physical, temporal nature, in our own comfort and pleasure, we reap corruption and death (Php 3:18-19); if we choose life and walk in the light as a manner of life, we reap everlasting life. (Ro 2:6)
The law of sowing and reaping: we reap what we sow, we reap more than we sow, and we reap later than we sow. It’s a universal truth; no one escapes it, not even through the Gospel. So, the apostle Paul warns us: “Be not deceived, God is not mocked: for whatsoever a man soweth, that shall he also reap. For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.” (Ga 6:7-8)
So, how does this work in Christ? When God forgives us, does He deliver us from the consequences of our choices? No; even those in Christ are subject to this law: no one is exempt. (Col 3:23 -25) Why must this be?
God chastens and scourges every child He receives (He 12:6) to break the pattern of selfishness and disobedience, and work righteousness in us. (He 12:10) God’s law is for our good (Ro 7:12), and when we break it, or sin, this is bad for us. God is intent on delivering us from the power of sin as well as from its penalty; so, if we’re sowing in the wrong place, God will often use this law of sowing and reaping to help straighten us out. The natural consequences of our choices are often our best teachers.
Certainly, God is merciful to all of us (La 3:39): we never reap the full consequences of our sin in this life. (Ps 103:10) For those who fear Him, His mercy is infinite. (Ps 103:11)
But those who commit themselves to a life of sin, sin of any kind, show themselves to be alienated from God, subject to His wrath and indignation (Ro 2:8); it reveals that they’re not God’s children. (1Jn 3:9) God transforms His elect such that they live to please Him. (Ep 2:10)
Thinking anyone can sin without consequence is to deny the justice of God, making a mockery of His dignity and His eternal Word. It makes Him out to be a liar. For anyone who tries this, it will not end well. God does not tolerate being mocked like this; His fiery indignation will silence every rebellious tongue, terrify every arrogant heart, and devour every adversary. (He 10:27)
