That God is the Judge of all is not necessarily a frightening thought. As Judge, God embodies justice. He rewards good and evil accordingly. Although none of us is perfect, when we surrender ourselves to Jesus (Yeshua‘), His shed blood counts as the penalty for our sins. God accepts us because of Jesus’ sacrifice. Justice has been done on our behalf; our penalty has been paid. Only when people do not receive Jesus does a fear of judgment remain. God judges everyone, but the outcome is different.
