Luck is not a Christian concept. God is sovereign. God chose you for salvation before the foundation of the world. It had to happen. Luck had nothing to do with it.
Ephesians 1:3-6 ESV
[3] Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, [4] even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love [5] he predestined us for adoption to himself as sons through Jesus Christ, according to the purpose of his will, [6] to the praise of his glorious grace, with which he has blessed us in the Beloved.
