We can not see it but yet we know it's there. Hebrews 12:1 Jesus, Founder and Perfecter of Our Faith Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, If you had to describe gravity to someone how would you do it? By itself it can not be seen. The effects of it is how we know it to be true. Sin can be compared to the effect it causes. You can not show someone sin but you prove it true by what you see. Point to a broken family, a corrupt group of people or the mirror. We all are effected by sin. It is only those that live in Christ that can be set free from the cintro of sin. To heal, grow and be transformed into the image of Christ is the Father's goal. Without the shedding of blood there is no forgiveness of sin. Only Jesus.
