There is Easter in the Commandments, because the Decalogue describes exactly what the new life looks like—loving God with heart and soul and mind, loving our neighbor as ourselves—the life of the saints of God in Christ, who has made us new.
But at the same time there is Good Friday in the Commandments. They show us our sin and they condemn us. Each of the 10 is like a nail of the cross piercing us with its demands of what our sinful nature ought to do, but does not do very well at all; what our sinful nature ought not to do, but still finds a way.
So we Lutherans, if we are true to our name, we neither do away with the Law of God, nor do we turn it into a Christian slavery. We always look upon the commandments in Christ.
