In Christianity, the root of all sexual sins is a selfish obsession to ones own desires and gratification. In one sense, Self-love is the root of all sexual immorality. So the way to fight sexual sins in our relationships in the church and in our marriages is to learn to love others and understand what it means to love them. Sacrificial love towards our spouse is the way to fight sexual temptation.
Christian life is always about believers strengthening each other in the Lord. Sometimes a Christian need to initiate or be the source of encouragement in another’s life. In this passage, we see how Ruth’s godliness and her devotion revives Naomi’s Spiritual health, which in turn enables Naomi to take initiative in progressing Ruth’s life.
