20: making my recourse to my God, who is our only security

Donne suggests in his last few lines that to think about our own death/misery is not enough because oftentimes we do not think of these things until we are dying ourselves. We must also take thought of others' miseries and deaths. Through suffering and sacrificing in others' miseries, we become closer to God. By considering the fate of others as they pass from the earth, our thoughts turn closer to God and our own afterlife. Donne concludes by suggesting that God is the only Being that can ensure our existence beyond this life.
