A resource is a source of supply, support, or aid, especially one that can be readily drawn upon when needed. When one considers resources he is usually considering things like money, or any property that can be converted into money; assets. The question in title aims to address the resources that are of the spiritual kind.
Your Spiritual Resources are Treasures
Everything on the Earth is temporal. All that the world and its religions give pertain to the externals. Your spiritual resources reside in the spirit, which is the light of the soul. If your spirit is devoted to God alone, your soul will be full of light; never lacking. Jesus is the Way, Truth, and Life (John 14:6) Develop a relationship with Him. He says,'Whosoever drinks of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into Everlasting Life.' Jesus deals with the core of man's being, and is a perennial fountain; never ending resource.
Treasures in Heaven
Lay not up for yourselves treasures upon earth where moth and rust does corrupt, and where thieves break through and steal. But lay up for yourselves treasures in Heaven, where neither moth nor rust does corrupt, and where thieves do not break through nor steal: For where your treasure is, there will your heart be also (Mathew 6:19- 21). keep your heart with diligence; for out of it are the issues of life (proverbs 4:23).
