Well, just reading the lives of the saints gives us a very good idea of why we seek God, although not everyone seeks Him for the same reason, but it’s because we are only truly happy and at peace with Him, He is the only one who can truly satisfy us, because he made us for Himself, He is our purpose and our place,
“Who except God can give you peace? Has the world ever been able to satisfy the heart?” St. Gerard Majella
“No earthly pleasures, no kingdoms of this world can benefit me in any way. I prefer death in Christ Jesus to power over the farthest limits of the earth. He who died in place of us is the one object of my quest. He who rose for our sakes is my one desire. Do not talk about Jesus Christ as long as you love this world.” St Ignatius of Antioch
“You cannot please both God and the world at the same time, They are utterly opposed to each other in their thoughts, their desires, and their actions.” St. John Vianney
The saints saw such beauty and joy and love in God, that the world became detestable to them…not the world as the “earth”, but worldly things, especially what leads into temptation, the world, the flesh, and the devil, and then since they found such joy and peace in God, the joys of this world paled…of course that does not mean that the things we find joy in in this life are bad, it simply means that the more we love God and desire to be with him, the more those things no longer impress us or have hold on us,
although some may think that that kind of holiness is to hard to reach, that being a saint is only possible for a select few…but don’t be fooled by those kinds of thoughts, the devil likes to hold us back by feeding us those lies…because in all honesty, anyone can be a saint(i know a saint is someone who is in heaven, but you know what i mean)…and where someone may not think so is because when they read the lives of the saints, they see the miracles and visions and extraordinary things, and think that’s what a saint is…but really what makes you “saintly” is in your virtues, not just the ones others see, but above all, the ones God sees, the ones you practice in your heart, such as charity towards your neighbor, truly forgiving all who have offended you from your heart,
well, i’m getting off subject…so to just put it simply, we seek God to love him, and to be happy, though not necessarily in this life, but in the next.
and yes, we are weak and completely dependent on God to do anything good, so if we wish to even love Him more and grow in the virtues, we must ask.
