Matthew 28:16-20
The Great Commission
16 Then the eleven disciples went to Galilee, to the mountain where Jesus had told them to go. 17 When they saw him, they worshiped him; but some doubted. 18 Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. 19 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, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."
In the Gospel According to St. Matthew, St. Matthew writes that Jesus told them to go to Galilee...He had told Mary Magdalene and the other Mary to tell the brothers to go to Galilee and there they will see Me (Matthew 28:10)...So the Mary's told the Eleven...The disciples go to the mountain in Galilee...
When the Eleven saw Him on the mountain in Galilee, they worshipped Him, but some doubted...There Jesus is right in front of the Eleven brothers and some are doubting...Even when we see things sometimes, they are hard for us to understand, and the disciples were there seeing and hearing...
The original Twelve disciples were given much evidence over a period of three years, and now Jesus had resurrected and was with them and talking with them...THEY WERE EYEWITNESSES for three years and were eyewitnesses now to His Majesty...Yet, some doubted...This should give us hope about our faith...We may have days when we our faith is not as strong as other days...When we don't understand things we have a tendency to doubt...There is a link between faith and understanding, but it is only a link...We tend to believe in things we understand...However, Jesus teaches us that there will be things we don't understand, and yet we are have faith...In John chapter three, Jesus teaches Nicodemus an Israeli teacher...Jesus tells Nicodemus in verse ten that were things he (Nicodemus) did not understand about the Holy Spirit and being born (again) of the Spirit...But because we don't understand things, doesn't have to effect our faith (however, often it does)...We must remember to keep our faith during the times and situations, when we don't understand...Nicodemus kept the faith and helped bury Jesus with Joseph of Arithmathea (John 19:39)...
Even though some of the disciples doubted, Jesus said to them "All authority in heaven and on earth has been given to Me"...Jesus had all authority...Next He told them to go and make disciples of ALL nations, and to baptize them in the name of the Father, the Son, and the Holy Spirit...When Jesus here mentions the Father, the Son, and the Holy Spirit, we have mention of the Trinity...The Trinity is belief that God is of three parts, the Father (God), the Son (Jesus), and the Holy Spirit...Jesus tells the Eleven to baptize in all three names, and not just one...
Then Jesus tells the Eleven to obey everything He had commanded, and that He will be with the Eleven till the end of times...He will not leave them, when they die, but always to the very end of age...At the end of age Jesus will return in the sky and we will see Him again (Matthew 24:30)...
This is a great promise to the Eleven (even though some still are doubting) that He will always be with them...The Eleven are no longer physically on earth...This is now a great promise to us...He will be with us forever...He wants us to continue to make disciples of all nations, so everyone has heard of the Father, the Son, and the Holy Spirit and follow His teachings...
