Last Sermon of Jesus
John 14:6 Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me."
John 8:31-32,36 Then Jesus said to those Jews who believed Him, "If you abide in My word, you are My disciples indeed. And you shall know the truth, and the truth shall make you free....Therefore if the Son makes you free, you shall be free indeed."
If we obey and keep (abide) His word then we will know the truth, which will set us free from the flesh, worldliness, wickedness, falsehood, lies, covetousness, addictions and bad habits, fears, doubts, unbelief, deceptions, bondages, etc.
Mark 4:34 But without a parable He did not speak to them. And when they were alone, He explained all things to His disciples.
All this while our Lord Himself taught His disciples the mysteries and truth hidden in His parables.
Luke 18:28 Then Peter said, "See, we have left all and followed You."
His disciples obeyed and followed Him all these years, but still they were not able to know the truth because they had not yet received the Spirit of truth (another Helper).
John 14:15-17, 26; 16:3 "If you love Me, keep My commandments. And I will pray the Father, and He will give you another Helper, that He may abide with you forever— the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you... But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you... However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come."
When we love Him (by keeping His words and commandments) at the request of our Lord Jesus, God will give us the Spirit of truth.
Acts 1:5, 8 "for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now... But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth."
Our Lord instructed His disciples who loved Him, to wait until they had receive the power of the Holy Spirit. So immediately after the baptism of the Holy Spirit, His disciples, having known the truth (knowledge and understanding of the mysteries and wisdom of God), preached the gospel boldly and fearlessly.
Brethren, when we keep His word and commandments, our Lord will baptize us with the Holy Spirit (Spirit of truth), Who will guide and teach us the truth hidden in the words, teachings and parables of Jesus.
Note: - Devout Jews (non Christians) filled with the Holy Spirit were given the gifts of the Holy Spirit, but only those baptized in the Holy Spirit know the truth.
Acts 2:6-8 And when this sound occurred, the multitude came together, and were confused, because everyone heard them speak in his own language. Then they were all amazed and marveled, saying to one another, "Look, are not all these who speak Galileans? And how is it that we hear, each in our own language in which we were born?
Luke 1:41 And it happened, when Elizabeth heard the greeting of Mary, that the babe leaped in her womb; and Elizabeth was filled with the Holy Spirit.
Luke 1:67 Now his father Zacharias was filled with the Holy Spirit, and prophesied...
