The healing of the centurion's servant is one of only two miracles that Jesus did for Gentiles, and He is especially taken with the Roman officer's faith.
This Roman officer seems to have understood an aspect of God's authority and power that even most Israelites never realized.
When the Roman centurion sent his emissaries to ask Christ to heal his servant, Jesus responded with great praise for the centurion's faith.
We must establish an iron clad trust in God for spiritual matters, including healing, rather than having a misguided trust in self or other human beings.
Sometimes we make things a bit too theological, wanting to know all the details of a doctrine, but simple faith is trusting God and believing His word.
The Jews believed that they had a natural right to the privileges of God's kingdom. They called themselves, therefore, "the children of the kingdom."
The parables of the leaven and the treasure hidden in the field show two sides of the same coin. The hidden treasure is the God-given solution to the leaven.
In Matthew 13, the hidden treasure the man finds provides the spiritual solution to the leaven - corruption - the woman hides in the three measures of meal.
God has gifted all His called-out ones, expecting them to use those gifts with the pillars of godly wisdom for the edification of the Body of Christ.
