Romans 6:19-23 / Luke 12:49-53
Every person grows with age. The growth is just not physically, but also intellectually, emotionally and spiritually.
Although a person's growth can be measured most obviously by the age, it does not necessarily mean that with age there will be maturity.
It also does not mean that as one gets older, one also get wiser, or mellower, or holier.
And if one is not formed in good moral principles, then, as the 1st reading would put it, they are like slaves of sin, with no obligation to righteousness.
The result would be actions that are embarrassing to say the least, and even at the far end, it would be actions that result in destruction of self and spiritual death.
The 1st reading reminds us that we have been set free from sin, and with God as our Master, we are lead to our sanctification and ending with eternal life.
In short, it is clear that sin leads to death, but when we surrender ourselves to God and walk in His ways, we are rewarded with eternal life with Christ Jesus our Lord.
So as we grow in age, let us also grow in wisdom and understanding, and be a spiritually matured people.
Let us continue to grow spiritually by walking in the ways of the Lord and walk towards eternal life in Him.
