Ephesians 1:11-14 / Luke 12:1-7
In the Creed, we profess God is the maker of heaven and earth, of all things visible and invisible.
So in the reality of our world, there are things that we can see and things that we can't see but we know that they exist, eg. air.
But there is also the reality of the spiritual world which we know exists but because it is the spiritual world, it can't be measured or quantified.
Even for ourselves, as much as we have a physical reality, we also have a spiritual reality.
The 1st reading states that we have been stamped with the seal of the Holy Spirit. This seal certainly cannot be physically seen or measured.
But as Jesus said in the gospel: Everything that is now covered will be uncovered, and everything now hidden will be made clear.
The Holy Spirit is the pledge of our inheritance, which brings freedom for those whom God has taken for His own, to make His glory praised.
Although stamped with the seal of the Holy Spirit, we can still cover it and make it ineffective by living a life that is not pleasing to God and not giving glory to God.
Among other sins, we do that by hypocrisy which in essence is living in falsehood and with lies, but it is not a life lived in freedom of the truth.
Jesus tells us to beware of this sin of hypocrisy because it will cost us our inheritance of eternal life with God.
Rather let us live our lives under the direction of the Holy Spirit so that we can live in freedom and give glory to God always.
