The Book of Hebrews is all about seeing the supremacy of Jesus Christ, so that we will come and satisfy ourselves in him. No one else measures up to him. No one else is able to accomplish what he did, when he went to the cross. No one else is able to bear that burden and deliver us from the punishment our sin deserves. No one else is able to perfect us, so that we may enter, without fear into the presence of God, to have that fellowship with him that we were created and intended by God to have.
