Christ's invitation to the weary and heavy-laden is a call to begin life over again upon a new principle--upon His own principle. "Watch My way of doing things," He says. "Follow Me. Take life as I take it. Be meek and lowly, and you will find Rest."
Whatever rest is provided by Christianity for the children of God, it is certainly never contemplated that it should supersede personal effort. And any rest which ministers to indifference is immoral and unreal--it makes parasites and not men.
Men sigh for the wings of a dove, that they may fly away and be at Rest. But flying away will not help us. "The Kingdom of God is WITHIN YOU." We aspire to the top to look for Rest; it lies at the bottom. Water rests only when it gets to the lowest place. So do men. Hence, be lowly.
The external observance of the Sabbath rest is a Jewish ceremonial ordinance and no longer binding on Christians. Sabbatarians surpass the Jews three times over in a crass and carnal Sabbatarian superstition.
