Jesus, full of the Holy Spirit, returned from the Jordan, and was led by the Spirit into the wilderness
The view that Christ COULD HAVE SINNED is expressed by the word PECCABILITY; the view that it was impossible for him to have sinned is expressed by IMPECCABILITY.  The view here is that the capability of Jesus to commit sin was a necessary and inherent result of the incarnation, in exactly the manner as was his mortality.  "Temptation in Christ indicated the possibility of sin."[2] If it was impossible for Christ to sin, how could there have been any temptation?  No man can be tempted to do that which it is impossible for him to do; but Christ was tempted in "all points" like as we are tempted  (Hebrews 4:15).  The emotional treatment of this subject by some who hold the contrary view is represented by the words of Best, "A peccable Christ would mean a peccable God";[3] but this is not logical, being equivalent to saying that a mortal Christ is equivalent to a mortal God. See more extensive treatment of this subject in my Commentary on Hebrews,  Hebrews 4:14.
