Infirmity can be an expression of depression. In the Ancient Days people were ruled harshly by their masters. Many did not dare to stand up, to be happy, for the happy person is vulnerable. They were in submission, because they were pressed down (depressed) by their masters. They were deaf and dumb, without energy or motivation. They appeared feeble, which is the meaning of the Greek word astheneia which was translated as infirmity in today’s reading. Even today depression is seen as a disease and amongst those who were healed by Jesus there would have been many sufferers of this condition and through the touch of the Son Of God, their minds were opened to faith and joy!
Today’s reading is about Jesus and his compassion on the ignorant, and on them that are out of the way. He was born a man so that he himself was also compassed with infirmity.
 For every high priest taken from among men is ordained for men in things [pertaining] to God, that he may offer both gifts and sacrifices for sins:  Who can have compassion on the ignorant, and on them that are out of the way; for that he himself also is compassed with infirmity.  And by reason hereof he ought, as for the people, so also for himself, to offer for sins.  And no man taketh this honour unto himself, but he that is called of God, as [was] Aaron.  So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee.  As he saith also in another [place], Thou [art] a priest for ever after the order of Melchisedec.
In Luke 13: 11 ’there was a woman which had a spirit of infirmity eighteen years, and was bowed together, and could in no wise lift up [herself].’ Why was she like that? Had she been suppressed? Had she become depressed so that she did not dare to face anybody? Verses 12 & 13, ’And when Jesus saw her, he called [her to him], and said unto her, Woman, thou art loosed from thine infirmity. And he laid [his] hands on her: and immediately she was made straight, and glorified God.’
The loving touch of Jesus made her well. In Luke 4: 18 Jesus read from the book of Esaias, ’The Spirit of the Lord [is] upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised.’ and he said (verse 21), ’This day is this scripture fulfilled in your ears.’
Jesus was there to preach deliverance to the brokenhearted and the captives! The Gospel should make us free of suppression, free of depression! Can we free others? According to Acts 1:8 we should receive power, after receiving the Holy Ghost.. However, it should not turn us into contemptuous people criticising everything and holding others in low esteem and despising what we don’t understand. We still should walk in Humility.
