The urgency is even greater as we age: We may not have many years left in which to glorify Him before we are buried. So, here's my New Year's resolution, a paraphrase of Jonathan Edwards' statement in Religious Affections: To maintain a conviction so clear as to induce me to venture forth with boldness, counting any problems insignificant in comparison to the joy of proclaiming Christ's glory.
That helps me to define what I hope is the arc of my life: Learning (with rash starts and sinful stops) to trust God. The Bible is full of the demand to trust. Two thousand years ago Joseph and Mary, when she became pregnant, trusted God: Their arc included putting up with a lifetime of gossip about the circumstances of Jesus' birth. Two thousand years before that Abraham trusted God: His arc led him to become an ancestor of Christ. Before that Noah's arc led him to the Ark, whole-hearted trust in the Lord.
What's your individual mission statement? To paraphrase pastor Tim Keller, are you looking to Christ as an add-on, someone to spruce up the cottage, clean out the gutters, slap on some paint? (And all the time we don't realize that God plans to make the cottage a palace.) Have you reacted to Jesus in a tepid way? (Because if you understand what He's saying and you have intellectual integrity, it's cowardly not to go all out in following Him.)
What's the arc of your life? If it's pointing you to anything other than resolutely entering the Ark, your resolution needs reconsideration.
