“What is the Gospel?”, a question of eternal consequences answered in three parts by Albert N. Martin.

Heb 2:1-4  Therefore we ought to give the more earnest heed to the things that were heard, lest haply we drift away from them.  For if the word spoken through angels proved stedfast, and every transgression and disobedience received a just recompense of reward; how shall we escape, if we neglect so great a salvation? which having at the first been spoken through the Lord, was confirmed unto us by them that heard; God also bearing witness with them, both by signs and wonders, and by manifold powers, and by gifts of the Holy Spirit, according to his own will.
