Former experiences of God's power and goodness are strong supports to faith, and powerful pleas in prayer under present calamities. The many victories Israel obtained, were not by their own strength or merit, but by God's favour and free grace. The less praise this allows us, the more comfort it affords, that we may see all as coming from the favour of God. He fought for Israel, else they had fought in vain. This is applicable to the planting of the Christian church in the world, which was not by any human policy or power. Christ, by his Spirit, went forth conquering and to conquer; and he that planted a church for himself in the world, will support it by the same power and goodness. They trusted and triumphed in and through him. Let him that glories, glory in the Lord. But if they have the comfort of his name, let them give unto him the glory due unto it.
The victories with which God blessed David over the enemies of Israel, are types of Christ's victory, for himself and for all believers. Those who take him for theirs, may see him acting as their God, as their King, for their good, and in answer to their prayers; especially in and by his word and ordinances. The kingdom of the Messiah shall be submitted to by all the rulers and learned in the world. The people seem to address the king, verse 28. But the words are applicable to the Redeemer, to his church, and every true believer. We pray, that thou, O God the Son, wilt complete thine undertaking for us, by finishing thy good work in us.
