Building faith require works and attention. Separation of spoils cannot be used in building and are burned away. A strong building is in the foundation of God. He is solid, and so shall the bricks that are branched into one's who abides inside as His temple. To abide in God means not giving a withered works, but works that are pure in strength, trust, and works that are kept focused with building with bricks of God's commandments of obedience to live by.
EVERY BRANCH:
Every branch in me that beareth not fruit he taketh away; and every branch that beareth fruit, he purgeth it, that it may bring for more fruit. Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me. If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned. --John 15:-6 KJV
