As soon as we limit our future to some particular moment in this fleeting world we experience a vain form of anxiety. Our true future is eternal life with God in heaven, and if we aim our souls at that unending moment we are delivered from all fruitless forms of anxiety.
Providence liberates us from the suffering caused by our believing that we will not have what we really need, but it does not spare us from the suffering that is a balm for our selfishness and pride.
Even that suffering which is occasioned unjustly at the hands of the enemies and adversaries of God calls the heart of the believer to dwell in peace beyond this valley of tears. The citizens of heaven are not spared torments here below, but from the depths of their hearts they can freely unite themselves with the King of Peace.
