John 17:20 "Neither pray I for these alone, but for them also which shall believe on me through their word;"In the powerful statement above, we read about Jesus putting His seal of approval on the apostles whom He entrusted to carry on His message after He ascended into heaven. Jesus was able to do this because of His foreknowledge of their future. If they would have strayed from His original intent for them to preach His unadulterated Word, He would have foreknown it, and accordingly would not have directed us to believe on Him through their word. Knowing this important truth, we can rest assured that His command for everyone to believe on Him through their word, means that they truly did teach how to believe on Him properly. Therefore, we must make sure we have believed on Jesus by adhering to what the apostles taught with regards to how we receive salvation. This book seeks to accomplish what Aquila and Priscilla did for Apollos as noted in the Book of Acts. Even though Apollos was walking in the "way" of the Lord, Aquila and Priscilla were able to show him that "way" more perfectly. Similarly, only when we stand on what the apostles preached to sinners as recorded in the Book of Acts, will we understand that "way" properly, since the Book of Acts is the only book in the entire Bible with their actual sermons to the lost after Jesus' ascension into heaven.In the Book of Revelation, the apostles' names are found written on the foundation of the New Jerusalem, along with the prophets and Jesus Christ being the Chief Cornerstone of that foundation. This is the illustrated version of what Paul said the Church is built upon today. We can trust their teachings! They revealed to us whether or not "doctrine" is something with which God wants us to be concerned. Learn what the apostles told sinners they must do to be saved, and understand that we are to share the exact same gospel message today.
