To gain eternal life is to participate to the fullest degree possible in the very life of God. It is to walk the path of love, surrendering to grace and allowing this grace to flow through you to the wider world. Is this an easy task? No. The Gospel of Luke tells reminds us that the gate is narrow precisely because it is in the very shape of Jesus Himself, and entrance through the gate involves conformity to his state of being. The path of love is traveled by taking up one’s cross every day.
