God is not mocked means that His justice is unwavering and His truth will always prevail, especially regarding salvation.
To assert that God is not mocked underscores the seriousness with which He regards His own word and promises. In the context of Galatians 6, Paul warns that those who seek to earn righteousness through their own works reject the sufficiency of Christ’s sacrifice. This mockery leads to dire spiritual consequences, as one cannot deceive God by attempting to gain favor through self-righteousness. God’s sovereignty ensures that His righteousness will be manifested, and those who attempt to rely on their merits will reap corruption. It is a call to acknowledge the full sufficiency of Christ’s work and to embrace the grace God has provided through Him.
