I don't think anyone holds any illusions about this... but in the spirit of confessing faults one to another, I should probably confess that I'm sadly content to be like Moses and see the land. It's a great deal harder to be like Joshua and go into it.
The leaven of evangelicalism seems to me to be the notion that man in the flesh can please God. As I listen to preachers and teachers who consider themselves "evangelical", I notice two themes. The first theme is a dangerously compromised Gospel. Scripture teaches that God justifies the one who does not work, but believes (Romans 4:5). I have many times heard a "gospel" message that places some sort of work between the sinner and justification. Scripture doesn't call on the sinner to repeat a prayer, or to "invite Jesus into his heart." Scripture merely calls the sinner to believe. And to be clear: it calls the sinner to believe not something, but Someone.
The second theme is the idea that the justified sinner is now capable of obeying God, as a justified sinner. By contrast, what Scripture teaches is that those who have died with Christ are to yield their members to God as those alive from the dead (Romans 6:13). There is no pleasing God without going through death.
Scripture presents baptism as standing at the gateway to the Christian life. What is the truth of baptism? It is the fact of the believer's identification in the death, burial, resurrection, and public testimony of Christ (Romans 6:3–6; Colossians 2:12; 1 Corinthians 15:3–5). Baptism means my life has ended. And notice, it's really the first step in the Christian life. We don't work our way up to baptism, we start there.
A friend of mine once told me, "everything, even spiritual gift, must go through death for God to use it." I've thought about that long and hard, and I think he was correct. Really, isn't that the message of 2 Corinthians 4:10–12? The end goal of the Christian life is to have the life of Jesus manifested in our mortal bodies (2 Corinthians 4:10–11). The tool that God uses to bring that about is death: death works in us (2 Corinthians 4:12). Sadly, this seems to be the opposite of the evangelical view.
The fact is that Christ Himself taught this to Nicodemus (John 3:3). The problem is, we have done a masterful job of not really hearing what the Lord said. The point is not that we need to have a "born again" experience to get into the Kingdom. The point is that we need an entirely new life. That doesn't leave room for the "old" life. We've managed to convince ourselves that the Lord was describing an addition, not a replacement.
No one gets into the Kingdom of God intact.
