2 Nephi 31 (II)

2 Nephi 31:13 I know that if ye shall follow the Son, with full purpose of heart, acting no hypocrisy and no deception before God, but with real intent, repenting of your sins, witnessing unto the father that ye are willing to take upon you the name of Christ...then shall ye receive the Holy Ghost. What does it mean to act hypocrisy before God? I get that if you get baptized without actually being penitent, you will not receive the blessings, so that part is clear, but is there anything more here that applies to us after we are baptized? Suppose at the time you get baptized, you are truly humble, penitent, and desirous of fellowship with the fold of God, but you later lose that.  Is there a concern that you might be hypocritical after the baptism?  Perhaps when we partake of the sacrament?
