And, first, it is righteousness.
In another place it is said that, "The wisdom that cometh from above is first pure."
The object and aim of the Christian religion is to make men holy. That is first. The righteousness mentioned in the text is put first—before the joy and peace. And this is what the world demands of people who profess to be Christians, no less than God's law demands it. The world has no use or respect for Christians who are not righteous or for a Christianity that does not make men righteous.
When God comes into a human heart, He comes with power, with the power of God, and that is greater than all other power, and before it all opposing forces fall. The sins of men, such as avarice, or love of money; the lust of the flesh, such as gluttony, licentiousness, the hatred of fellowmen and the hatred of God, all these are broken and driven out when the spirit and power of God come in. There is not only this demand of God, then, for righteousness, but also ample supply of strength to meet it, and to meet it fully. Come, then, to God, you who are in bondage to evil habits, and who have striven in vain to deliver yourselves. You can not retain your evil practices and be a child of God. His first demand, His imperative demand, is righteousness, and if you have the will He gives the grace to attain it.
But this is not all. When you believe with your heart in Christ, the Holy Ghost is given you, and He brings, with the righteousness and holiness which God requires, also joy and peace. Yes, when you surrender to Christ, He makes you happy.
MATTHEW XI: 28.
"Come unto me all ye that labor and are heavy laden and I will give you rest."
1. The cry of all hearts is for rest, for contentment. Not only does the heart of humanity cry out for rest, rest, rest; their busy and tired hands and feet toil for it day and night, year in and year out.
It is for this that men labor through the days and weeks of summer's heat and expose themselves to the severities of winter's cold.
