Interesting section of reading yesterday in our 30 Days With Jesus. Matthew 8:5-13:
5 When he entered Capernaum, a centurion came forward to him, appealing to him, 6 “Lord, my servant is lying paralyzed at home, suffering terribly.” 7 And he said to him, “I will come and heal him.” 8 But the centurion replied, “Lord, I am not worthy to have you come under my roof, but only say the word, and my servant will be healed. 9 For I too am a man under authority, with soldiers under me. And I say to one, ‘Go,’ and he goes, and to another, ‘Come,’ and he comes, and to my servant,  ‘Do this,’ and he does it.” 10 When Jesus heard this, he marveled and said to those who followed him, “Truly, I tell you, with no one in Israel  have I found such faith. 11 I tell you, many will come from east and west and recline at table with Abraham, Isaac, and Jacob in the kingdom of heaven, 12 while the sons of the kingdom will be thrown into the outer darkness. In that place there will be weeping and gnashing of teeth.” 13 And to the centurion Jesus said, “Go; let it be done for you as you have believed.” And the servant was healed at that very moment.
A Roman Centurion is praised for his great faith. He knew what it was like to be in authority, having his orders followed unquestioned. I imagine he routinely gave orders and never even bothered to confirm they were carried out because he just knew they would be.
And he translates that life experience to his spiritual life. He knows the authority he has, recognizes that Jesus has even more authority, and insists that Jesus need not trouble Himself with traveling to the Centurion’s house.
I suppose praying is only part of the answer to our problems. The other half—perhaps the greater piece, actually—is believing that Jesus not only has the authority to answer our prayers, but that He will.
