The doctrine of the providence of God is practical, and reflecting on God’s providence, as Francis Turretin noted, is a ready means of consolation for believers.

[F]rom belief in providence arises the greatest consolation and incredible tranquility of mind for the pious. It causes them, resting peacefully in the bosom of God and commending themselves entirely to his paternal care, always to hope well from him in the future, not doubting but that he will ever perform the office of a Father towards them in conferring good and turning away evils: examples of which are given in David (1 S. 17:37; Ps. 13:1, 4, 6) and in Paul (2 Tim. 4:17, 18). They feel that under his protection (who has all creatures in his power) nothing is to be feared by them, while walking in their proper calling. Hence, neither supinely neglecting means, nor carefully trusting to them, but prudently using them according to his command, they cast all their care upon the Lord (1 Pet. 5:7), and in all their perplexities always exclaim with the father of the faithful, “The Lord will provide” (Institutes of Elenctic Theology, Vol. 1, 538).
