12 I assure you and most solemnly say to you, anyone who believes in Me [as Savior] will also do the things that I do; and he will do even greater things than these [in extent and outreach], because I am going to the Father. 13 And I will do whatever you ask in My name [[a]as My representative], this I will do, so that the Father may be glorified and celebrated in the Son. 14 If you ask Me anything in My name [as My representative], I will do it.
15 “If you [really] love Me, you will keep and obey My commandments.
Role of the Spirit
16 And I will ask the Father, and He will give you another [b]Helper (Comforter, Advocate, Intercessor—Counselor, Strengthener, Standby), to be with you forever— 17 the Spirit of Truth, whom the world cannot receive [and take to its heart] because it does not see Him or know Him, but you know Him because He (the Holy Spirit) remains with you continually and will be in you.
18 “I will not leave you as orphans [comfortless, bereaved, and helpless]; I will come [back] to you. 19 After a little while the world will no longer see Me, but you will see Me; because I live, you will live also. 20 On that day [when that time comes] you will know for yourselves that I am in My Father, and you are in Me, and I am in you. 21 The person who has My commandments and keeps them is the one who [really] loves Me; and whoever [really] loves Me will be loved by My Father, and I will love him and reveal Myself to him [I will make Myself real to him].” 22 Judas (not Iscariot) asked Him, “Lord, what has happened that You are going to reveal Yourself to us and not to the world?” 23 Jesus answered, “If anyone [really] loves Me, he will keep My word (teaching); and My Father will love him, and We will come to him and make Our dwelling place with him. 24 One who does not [really] love Me does not keep My words. And the word (teaching) which you hear is not Mine, but is the Father’s who sent Me.
25 “I have told you these things while I am still with you. 26 But the [c]Helper (Comforter, Advocate, Intercessor—Counselor, Strengthener, Standby), the Holy Spirit, whom the Father will send in My name [in My place, to represent Me and act on My behalf], He will teach you all things. And He will help you remember everything that I have told you. 27 Peace I leave with you; My [perfect] peace I give to you; not as the world gives do I give to you. Do not let your heart be troubled, nor let it be afraid. [Let My perfect peace calm you in every circumstance and give you courage and strength for every challenge.]
