Samuel Logan Brengle addresses the concern of prioritizing one's own soul amidst the suffering and injustice in the world. He emphasizes that caring for one's soul is essential to avoid doubt and discouragement, and that through prayer and seeking the Holy Spirit, individuals can gain the strength and wisdom needed to help others effectively. Brengle encourages believers to wait on God for guidance and strength, asserting that one cannot assist others without first being filled with God's love and power. He cites the importance of taking time for personal communion with God, as neglecting this can lead to losing His presence and power. Ultimately, Brengle reinforces that self-care in faith is not selfishness, but a prerequisite for serving others.
