The Power of the Cross

i believe that the cross was actually how god defeated the enemy. It says that he put to death the enmity between heaven and earth with the cross. So why don't we preach about the cross more? We should, i think people are not feeling confident with it. What else is represented by the cross is the blood that was shed. And you know, jesus said that blood is so important. He said, i want you to drink fruit of the vine in memory of my blood being shed. You know, without the shedding of blood, is no remission of sins.
