"...we have been called to "take hold" of eternal life. There is urgency in our faith. True faith struggles to pry our hands off the old life and keep them on our eternal life. Biblical faith fights to believe the gospel to such a degree that it is reflected in our practice. Disciples fight to believe that Jesus' death and resurrection is our death and resurrection. His death is our death and his life our life (Romans 5; Galatians 2). As a result, the lie-believing, image-distorting life is dead, and in its place we have received a truth-believing, Christ-adoring life (Eph. 4:20-24). However, because of our tendency to return to the old image, we walk by faith until we see Jesus, when faith will correspond with sight (2 Cor. 5:6-7; Gal. 2:20). Until then, we fight, contend, and struggle. Believing the gospel is not a passive, one-time decision; it is an active, continual fight for faith in what God says is noble, true, and good."
