>Shouldn’t you focus on getting to god than wasting time to getting attached to worthless living life?
You should, but I don't think you understand the meaning of "getting attached". You should love everything and everyone in this world for the sake of God. You should be a good father/priest/worker, because that's what God expects you to do. If you have a comfortable life, give thanks to God, if your life is shit, give your suffering as an offering to God. Love your wife as God loves His Church, love your kids, because they are a gift from God, love your neighbour, because he is created in God's image.
If you say that "nothing matters", then the only Christian interpretation of these words would be "it doesn't matter for me if I'm rich or poor, hungry or full, hot or cold, because whatever happens, I'm in Christ and Christ is in me, so I'll keep spreading love and the Gospel as long as I'm alive". In no way should you get into gnostic memes about this world being evil in itself.
