Q. How can we enter into heaven without spot or wrinkle if we can’t stop sinning because of our sin nature?
A. At the moment of our resurrection / rapture, we will be made perfect (1 Cor. 15:50-53). Our sin nature will be removed. Today we are a new creation by faith (2 Cor. 5:17) When we arrive in heaven we will be a new creation in fact, perfect in every way. No part of our earthly imperfection will enter heaven with us.
