After His resurrection, Jesus appeared to His disciples, friends, and others.
Forty days after his body was resurrected, Jesus and His disciples went up to Mount Olivet where Jesus promised them that the Holy Spirit would come to give them strength and power in being witnesses to all nations for God's glory.
Matthew 28:19-20 “Therefore go and make disciples of all nations), baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you.
And surely I am with you always, to the very end of the age.”
After saying these things, Jesus ascended into heaven, meaning a literal bodily return to heaven. Many onlookers saw and bore witness on that day of Jesus's ascension.
As a cloud began to hide Jesus as he ascended, two angels appeared to the disciples and promised that Christ would
"come back in the same way you have seen him go into heaven."
" God elevated him to the place of highest honour and gave him the name above all other names, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord."
