Whenever someone implies that there are multiple tiers to salvation, I get suspicious. It's mainly due to a "once bitten twice shy" reaction to the deeper life/early Keswick theology which informed 40 years of my Christian life. This is one teaching that will rob you of your assurance and confidence in Christ. Why? Because there is an "initial" salvation that gets you in the door - forgiveness of your sins, but you need to haul yourself to the next level by your surrender. The act of surrender also needs to be a surrender in itself because "you" aren't supposed to do anything. Only "Christ" can. This becomes such a mess of spiritual pulse-taking to check if you are sufficiently dead to yourself. It then produces an underlying fear that never goes away because if you don't reach the next level, your acceptance into the kingdom is at stake. This particular twist is courtesy of the partial rapture teachings of D.M. Panton, and G.H. Lang....
