Make “every effort” …to rest.
Oh, how I love the Lord’s seeming contradictions – it keeps the fools away.
There remains, then, a Sabbath-rest for the people of God; for anyone who enters God’s rest also rests from his own work, just as God did from his.
Let us, therefore, make every effort to enter that rest, so that no one will fall by following their example of disobedience.
For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart. (Hebrews 4:9-12)
