A while back I listened to a sermon on relationships by the late Dr. Myles Munroe. Although I cannot provide a direct quote, I distinctly remember one of the points he made which struck a chord with me.
Dr. Munroe spoke about the different types of love; Agape, Philio, and Eros. He highlighted how couples who base their love solely on the physical aspect, Eros without cultivating the other forms of love, are inherently unstable. When the shallow roots are shaken, the entire "tree of love" topples.For any relationship to flourish, it needs a strong foundation of Agape love the kind of selfless, unconditional love that God has for us. Before you decide to share your life with someone, you need to cultivate this deep, devoted type of love for them.
This is the secret to a successful relationship, a love that is rooted in God's love, rather than fleeting physical attraction. Only then will you be truly willing to go to great lengths for your partner, and build a love that will stand the test of time.
