We often ask, "have you accepted Christ as your personal savior?" But we should be asking, "Have you accepted Christ as your King?" Unless we submit to being under Christ as our King, we can't truly experience Christ as our savior.
We aren't sinners because we sin, we sin because we're sinners. We have a choice; to die from sin and stay dead, or die to sin, and have life with Jesus.
When we judge and condemn others for their judgements, we are in the same category. We are measured against God's standards, not the standards of others.
