1The former treatise have I made, O Theophilus, of all that Jesus began both to do and teach,
2Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen:
3To whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God:
4And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me. – Acts 1:1-4
Acts reveals the resurrected Lord spending time with His disciples. He spent time with them, sharing vital truths with them regarding the kingdom of God. The Word says that it was forty days that they spent together.
Imagine spending a 40-day intensive with Professor Jesus Christ. Just think about it. Picture yourself spending 40 days, listening at the feet of Jesus in an intimate setting. Typically, we pay hundreds of dollars to hear gurus speak on all sorts of topics that may help us with evangelism or Vacation Bible School. These guys were in the presence of Jesus after He had risen from the grave.
You can study under Jesus, too. Spend some time getting together Him. Read His Word. Meditate on the Scriptures. get into them and get into discussion and dialogue with others about them.
Search the scriptures; for in them ye think ye have eternal life:
and they are they which testify of me.
– John 5:39
