Acts 13:40
Beware, then, lest what is spoken in the Prophets should come true of you:
Matthew 3:9-12
and do not imagine that you can say to yourselves, 'We have Abraham as our forefather,' for I tell you that God can raise up descendants for Abraham from these stones.
Hebrews 2:3
how shall *we* escape if we are indifferent to a salvation as great as that now offered to us? This, after having first of all been announced by the Lord Himself, had its truth made sure to us by those who heard Him,
Hebrews 3:12
see to it, brethren, that there is never in any one of you--as perhaps there may be--a sinful and unbelieving heart, manifesting itself in revolt from the ever-living God.
Hebrews 12:25
Be careful not to refuse to listen to Him who is speaking to you. For if they of old did not escape unpunished when they refused to listen to him who spoke on earth, much less shall we escape who turn a deaf ear to Him who now speaks from Heaven.
