This sentence implies that when you open your heart to accept God (usually referred to as the LORD), He enables you to see or understand the plight of the lost or misguided individuals in your life. It means that by embracing divine love and compassion, you gain a deeper awareness of the needs and challenges of those who have strayed from the right path. In other words, as you become closer to God, your heart becomes more open and sensitive, allowing you to better recognize the struggles and sufferings of others. This recognition then motivates you to assist or guide those who are lost, helping them find direction and purpose.
