Paul said that we will be changed. In a moment, the trumpet will sound and the dead will be raised. This perishable nature will put on imperishability. Our mortal nature will become immortal. In immortality, death will be swallowed up. Death will lose its sting. Death will be conquered. Death will have no victory. The sting of death is sin. This victory comes from our Lord Jesus Christ. We have to remain steadfast in the work of the Lord, where there is no labor in vain.
