As with most things in our experience the nub of the issue involves the cross. We need to be clear not just about Christ’s death but about our own also. First, we have to accept the fact that only Jesus can take away the guilt of our sin. Then we have to be clear that Jesus died for us not merely to reconcile us to the Father but to transform us into his likeness. As soon as we understand this, we realize that the height of Christian experience is not the forgiveness of our sins—though that is the indispensable “door” that Jesus speaks about (cf. John 10, Rev. 3). To be properly human we need first to accept this unique salvation and to hold onto it throughout our lives, for it is the rock upon which all else rests. But what follows is equally important. Jesus says, “You therefore must be perfect, as your heavenly Father is perfect” (Matt. 5:48). Paul says, Therefore be imitators of God, as beloved children. And walk in love, as Christ loved us (Eph. 5:1–2). God welcomes us into his family not to provide us with rest and relaxation, but in order to change us into his likeness. Not that the rest isn’t real, as Isaiah makes clear: “in repentance and rest is your salvation” (Isa. 30:15, NIV). We never work for our salvation the way man-made religions require. But alongside the rest comes our repentance. We commit ourselves to undergo, at God’s hand, a process of gradual transformation, of continual repentance, of laying aside what is un-human so as to become properly human. On one hand this means becoming like Jesus in positive virtues, on the other it means being willing to die with him and to imitate his sufferings. He was kind, just, patient, generous, merciful, and all the rest. He was prepared to go to the cross. We have to become like that too, though always conscious of our shortcomings.
