This lesson picks up with Christ's ascension into heaven when over 500 people witnessed this astounding sight. Two angels suddenly appeared to give the disciples an important message--Jesus is coming back. As real as was His ascension, so will be His second coming. Then the disciples obeyed our Lord's final command before He ascended and went into Jerusalem to tarry until they received the promised Baptism in the Holy Spirit. This is a soul-stirring lesson.
