Lean in

HEB 10:39 NIV
But we do not belong to those who shrink back and are destroyed, but to those who have faith and are saved.

Greg uses the phrase "lean in" to describe a predetermined attitude of choosing to draw closer to the Lord in spite of suffering or apathy.

But how do you actually will yourself to lean in? 

Perhaps these preceeding verses are applicable:

HEB 10:24-25, 36 NIV
And let us consider how we may spur one another on toward love and good deeds, not giving up meeting together, as some are in the habit of doing, but encouraging one another—and all the more as you see the Day approaching. ...  You need to persevere so that when you have done the will of God, you will receive what he has promised.

I think that the group of people with whom you spend significant time is the most significant spiritual influence in your life.  If the group is really devoted to growing in the Lord (not just cruise control), then it will incubate a spirit of pursuit.  Brandi and I are in a group like that now.  It is very encouraging.

Heavenly Father, thank you for inviting us to pursue you.  And thank you for the spiritual group that you have given us.  May we go on to greater heights with you.   I love you, and I pray in the name of Jesus Christ.
