The life that Christ has called us into is a life that is not just everlasting in duration. The eternal life that He welcomes us into is qualitative. Jesus says that He is the resurrection and the life, and that life is one that the Holy Spirit weaves us into. This affects the texture and the breadth of our lives—for it is intended to. Our natural resistance to this is one the things that God deals with in us.
We want to walk with our heads down, as though we were walking along a railroad track, keeping our balance there; we don’t want to live expansively, the way a Christian ought to live. We forget that God is sovereign over all things, and we forget that He is the God of dangers, the God of adventures, the God of the unexpected. The wrong kind of concern for safety, for security, for a life of predictable and cozy conservatism is, at the end of the day, a form of idolatry.
Think of it this way. Remember this exhortation as you understand the tasks before you—your vocation, your family life, your worship of God. Everyone here will live the entire length of their lives. Everyone lives until their dying day. All of us go the appointed distance. But not all of us live the width of our lives.
