The right words at the right time is not the only power of the Holy Spirit given us at the time of salvation. The Holy Spirit also not only teaches us but reminds us of all that God has done. ...
Jesus, according to John, before the crucifixion
14:15 If ye love Me, keep My commandments. 16 And I will pray the Father, and He shall give you another Comforter, that He may abide with you for ever; 17 [Even] the Spirit of truth; whom the world cannot receive, because it seeth Him not, neither knoweth him: but ye know him; for He dwelleth with you, and shall be in you.
15:26 But when the Comforter is come, whom I will send unto you from the Father, [even] the Spirit of truth, which proceedeth from the Father, He shall testify of Me: 27 And ye also shall bear witness, because ye have been with Me from the beginning.
16:7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send Him unto you. 8 And when He is come, He will reprove the world of sin, and of righteousness, and of judgment: 9 Of sin, because they believe not on Me; 10 Of righteousness, because I go to My Father, and ye see Me no more; 11 Of judgment, because the prince of this world is judged. 12 I have yet many things to say unto you, but ye cannot bear them now. 13 Howbeit when He, the Spirit of truth, is come, He will guide you into all truth: for He shall not speak of himself; but whatsoever He shall hear, [that] shall He speak: and He will shew you things to come. 14 He shall glorify Me: for He shall receive of Mine, and shall shew [it] unto you.
17:20 Neither pray I for these alone, but for them also which shall believe on Me through their word;
Jesus, according to Matthew, after the return
28:18 And Jesus came and spake unto them, saying, All power is given unto Me in heaven and in earth. 19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, [even] unto the end of the world.
