Hebrews 3:7-8 — “Wherefore as the Holy Ghost saith, To day if ye will hear his voice, harden not your hearts…” The writer to the Hebrews wanted to impress upon his readers the vital truth that through the Scriptures God the Holy Spirit speaks. If they were to continue in the faith and grow to maturity, they needed to recognise this and listen to what the Spirit had to say.
In the quotation from Psalm 95 that follows, the Hebrew Christians were charged not to allow sin to harden their hearts. This was an urgent message then and it remain so. Every Christian needs to listen “today!”
