Joshua 24:13 (Berean Study Bible)
I gave you a land on which you did not toil.
How does one feel when they win the. lottery or receive an inheritance? Ones feelings could vacillate between euphoria and a sense of undeservedness. The grace of God and the sacrifice of Christ is something similar. We can never earn our salvation, an innocent Man had to die for us. But, we shouldn't feel so lowly that we reject that grace either. As much as the grace of God is something we haven't worked for, that much it should be received with thanksgiving and not guilt.
