The cooperation makes the person happy and fulfilled
Cooperation
Wounded by sin, the man stands in need of salvation coming in Christ and of His grace and sustainment to work for good.
He must stay awake and watch, because the judgment follows the only death; he must live in peace with God and with everybody because he is responsible for the immortality of his soul.
The reality of death must make us seek future life without sadness, knowing and experiencing the richness of faith.
