Matthew 3:15 Jesus replied, "Let it be so now; it is proper for us to do this to fullfill all righteousness"
I'm not sure about your Bible, but in my Bible these are the first words in RED. This is the first direct quote from Jesus (at least in the ordering of the books of the Bible) in the Bible.
Jesus came to be baptized by John the Baptizer and John said "I need to be baptized by you, and do you come to me?" John's calling was to prepare the way for the Lord (Isaiah 40:3) and part of that calling included baptizing Jesus.
Are you pursuing your calling or your potential? There are so many things each of us have the potential to do in this lifetime. The number of things we can do, that we can pursue are endless. We can get so caught up in that "keeping up with the Jones'" pursuit of our potential that we forget to pursue our calling.
I think it's very fitting that the first words in red are Jesus telling John to continue in his calling to prepare the way of the Lord. Now if John wouldn't have pursued his calling, I'm sure that God would have figured something else out, someone else would have baptized Jesus. So He doesn't need us to pursue our calling to accomplish his work, but he wants us to pursue our calling to accomplish his work.
How much more fruitfull would be pursuing your calling versus your potential? How much more happy would you be?
Are you following your calling?
"Let it be so now..."
