What sparks (real) unfeigned love?

“When there is a vested interest and a certain type of lively effort that can only come from God, then that is a step for love to be shown out of.” - G.S.Ministr

What does ministering entail? How to inherit the promise?

for God is not unrighteous to forget your work, and the labour of the love, that ye shewed to His name, having ministered to the saints and ministering; and we desire each one of you the same diligence to shew, unto the full assurance of the hope unto the end, that ye may not become slothful, but followers of those who through faith and patient endurance are inheriting the promises. (YLT)

Romans 12:9 (WEB) #Step

9 Let love be without hypocrisy. Abhor that which is evil. Cling to that which is good.
