Preachers are called to teach the word of God, not their own interpretations. They must read the text, explain the text, and apply the text. In John 7:37 there is a common misconception that Jesus is referring to Acts chapter 2 and the filling of the Holy Spirit. But when we actually read this text we see that our Lord was calling people to Himself, promising them the gift of His Spirit unto eternal life.
On the last day of the feast, the great day, Jesus stood up and cried out, “If anyone thirsts, let him come to me and drink. Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water.’ ” Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified.
Simeon Peter, a servant and apostle of Jesus Christ,
To those who have obtained a faith of equal standing with ours by the righteousness of our God and Savior Jesus Christ:
May grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord.
His divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us to his own glory and excellence, by which he has granted to us his precious and very great promises, so that through them you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire.
