(1.) This may be understood of the kindness they had for God; it was not such indeed as they had any reason to boast of, or to plead with God for favour to be shown them (for many of them were very unkind and provoking, and, when they did return and enquire early after God, they did but flatter him), yet God is pleased to mention it, and plead it with them; for, though it was but little love that they showed him, he took it kindly. When they believed the Lord and his servant Moses, when they sang God's praise at the Red Sea, when at the foot of Mount Sinai they promised, All that the Lord shall say unto us we will do and will be obedient, then was the kindness of their youth and the love of their espousals. When they seemed so forward for God he said, Surely they are my people, and will be faithful to me, children that will not lie. Note, Those that begin well and promise fair, but do not perform and persevere, will justly be upbraided with their hopeful and promising beginnings. God remembers the kindness of our youth and the love of our espousals, the zeal we then seemed to have for him and the affection wherewith we made our covenants with him, the buds and blossoms that never came to perfection; and it is good for us to remember them, that we may remember whence we have fallen, and return to our first love, Rev. ii. 4, 5; Gal. iv. 15. In two things appeared the kindness of their youth:—[1.] That they followed the direction of the pillar of cloud and fire in the wilderness; and though sometimes they spoke of returning into Egypt, or pushing forward into Canaan, yet they did neither, but for forty years together went after God in the wilderness, and trusted him to provide for them, though it was a land that was not sown. This God took kindly, and took notice of it to their praise long after, that, though much was amiss among them, yet they never forsook the guidance they were under. Thus, though Christ often chid his disciples, yet he commended them, at parting, for continuing with him, Luke xxii. 28. It must be the strong affection of the youth, and the espousals, that will carry us on to follow God in a wilderness, with an implicit faith and an entire resignation; and it is a pity that those who have so followed him should ever leave him. [2.] That they entertained divine institutions, set up the tabernacle among them, and attended the service of it. Israel was then holiness to the Lord; they joined themselves to him in covenant as a peculiar people. Thus they began in the spirit, and God puts them in mind of it, that they might be ashamed of ending in the flesh.
