Our heart is our core or focal point, the hub of our human personality.
In this life there is unavoidable disappointments and trials. We can make a choice to let them define us, develop a hardened heart, or we can be strengthened through them.
“and we also exalt in our tribulations. Knowing that tribulation brings about perseverance; and perseverance, proven character; and proven character, hope; and hope does not disappoint, because the love of God has been poured out within our hearts through the Holy Spirit who was given to us.” Romans 5:3-5 (NAS)
Grace to you.
