“Men and brethren, this Scripture had to be fulfilled, which the Holy Spirit spoke before by the mouth of David concerning Judas, who became a guide to those who arrested Jesus;” (Acts 1:16, NKJV)
The Holy Spirit inspired the Holy Scriptures, and by them He speaks to us today. Do not expect the Spirit of God to speak to you through some “better felt than told” experience. The Holy Spirit will not give you an impulse of the heart apart from the Scriptures to convince you to follow the Lord. He speaks to us all in exactly the same way, by means of the words He put in the mouths of the prophets (2 Pet. 1:21). By these words the Holy Spirit speaks, convicting “the world of sin, and of righteousness, and of judgment” (Jno. 16:8). Listen to what the Spirit is saying to you. Read the Scriptures, gain understanding, and follow His will.
