Thy people shall be willing in the day of thy power, in the beauties of holiness from the womb of the morning: thou hast the dew of thy youth.
The old has the motivation of fear, if you don’t do good the axe will fall or if I do more and more good the reward gets better. As the Devil promised Eve you will be like God.
The day of power is the day of Christ, Christ came in the fullness of time to redeem man who all his life is subject to bondage, under the old covenant promise, do or die. In the new covenant Jesus as true man fulfilled all the demands of the law, went willingly to the cross taking our justly deserved condemnation made atonement for our sins in His blood, reconciling us to the Father. As new creatures in Christ, motivated by love we desire to obey God.
Praise be to God for the covenant of Grace!
Martin Luther’s exposition on this verse says it well.
The scriptures speak of two periods: the first of weakness, which included those who lived under the law. At that time, men did not observe the will of God freely through love but in the spirit of servile obedience. That day became to them an unbearable load and burden, impossible to enjoy. God’s will must be done without compulsion and that, in the nature of the case, was impossible for them.
The second period is the covenant of grace and help through which man is made strong, willingly observes the will of God and his commands, and sincerely loves him. Christians do this not for the sake of necessity or reward, nor do they fail through suffering or death. This is not the work of nature but of grace.
