St. Therese also had another analogy related to this question.
She said that each soul is unique to God’s eyes. Every one is much loved and indespensable. Each are given unique talents, strengths, weaknesses, experiences, etc. God is like a gardener who plants different kinds of flowers in his garden, and this precisely is what makes the garden beautiful and pleasing to God’s eyes. What would happen if all were roses? If all were orchids? But God made it so that everyone is different. Unique and precious in his eyes! I think this is why she called herself the little flower. She believed she was lacking in greatness, yet she also believed it pleased God all the same for God desired that it be so.
Let’s not compare ourselves to others. Someone said “The surest way to be unhappy is to compare yourself to others.” We will always find another who is more blessed in one respect. Also remember that material blessings is not everything that can be counted as God’s favor. God also bestows spiritual blessings, and sometimes this happens in the form of trials and sufferings. Some saints even said that these are signs of Divine favor and election because God is bent on purifying souls he allows to pass through these trials, as gold is perfected by fire. So let’s not compare and just thank God for his undeserved love. We don’t really know how much blessings God has bestowed on each soul. You will simply don’t know if this well to do person is more favored by God than you.
Indeed, God has certain favored ones. The Blessed Virgin Mary is one. But she is part of the One Body which is the Church, which we are also part of. Her favors are given also to benefit the entire Church. Because she had been so much blessed, made spotless, and favored by God, she became a strong intercessor and refuge of sinners. And aren’t we happy if one of our family members receives a great blessing? Whatever benefits they receive benefit us too. Let us just be happy that our brothers and sisters are receiving these favors. After all, If the “minimum” favor God gives a Christian is his dying on the Cross for our salvation, I don’t think it’s something to fret about.
