We are looking at this backwards, in a way. God knew from all eternity what would be our qualities, our strengths, our weaknesses, our response to every possible situation. Knowing this, and every circuмstance that would ever exist in the world, He specifically chose the time, place, parents and circuмstances in which to place us that would be most conducive to our spiritual good and that of those with whom we would be connected. There is no such thing as luck or chance.
God's providence takes in every factor, most of which we will never know on this earth. His aim is not to give us a comfortable life or physical security. His aim is for our eternal life. We ourselves do not know what we would do in a different set of circuмstances, but God does. God's knowledge and His love are infinite. Some people would grow hard and cold in more comfortable situations. Some would be proud and lost. Even those who will reject Him, no matter what, are placed where they do have opportunities for the truth, and in which they will accrue the least mortal sins. There is one thing we can do in every circuмstance, and that is continue to worship God as He wishes to be worshiped, strive to grow in holiness and closeness to our Saviour, cling to our Mother Mary, and do everything to the glory of God.
Someday in eternity this will seem so small, unless we use it to offer, united with the Cross of Jesus, our small sufferings for souls. That will make an eternal difference.
