Take hold of the eternal life to which you were called when you made your good confession in the presence of many witnesses.
It is one thing to believe with the promise of eternal life. It’s another thing to take hold of the eternal life, as Paul is saying here to Timothy. What this amounts to is living in a different world with feet solidly on the ground in the real world. And what’s involved in that is the presence of Christ in the world found in the church, the body of Christ. The groundbreaking for that was in Christ’s resurrection from the dead bringing the new life into the world destined to transform everything: the new creation in Christ.
Thankfully for us in Christ the real world is rooted in Christ. What is passing away seems front and center now, but not to us. What is front and center for us is nothing more and nothing less than the new creation in Christ. We live in a different world entirely. But to do so we too need to take hold of that world by faith. To live in that so that it permeates our lives through and through. But meant for this world, invading and somehow impacting the world through the presence and life of Christ in us. That others might see and believe. With impact on culture and judgment and final salvation to come. In and through Jesus.
