Why would Jesus come to him for baptism?
All of us want God to come and save us from a particular problem or difficulty. We wait for Him to come and solve our situation. Often we miss His coming.
Jesus show us that God works through other people. This is how God most often works. Jesus wanted to share totally in our humanity, including to allow God to work through others.
Maybe this is the day we watch for God working through others. Perhaps others will show us our lack of mercy and compassion. Or perhaps our not trusting God, etc.
This prophet tells us that one will come who will be a light to the nations; will open the eyes of the blind, will bring out prisoners, will be light to those who live in darkness. Certainly this is fulfilled in Jesus. But through our baptism Christ dwells in us. We are to make God present for others. We are to be a light for the nations. We are to open the eyes of the blind, etc.
I am sure that today God will work through others for each of us, but He will also call us to be the presence of God for others.
Watch how He will work in your life today.
