For he who does not love his brother whom he has seen, how can he love God whom he has not seen? (1 Jn 4: 20)
If you want to love God, start with love for people and serve them, respect them, and give yourself for them. Then you will find God's love has entered your heart automatically. Give love from all your heart to whoever needs love: to the children, the disabled, the elderly, the orphans, the needy, the poor, the handicapped, and those who have no one to remember them. Serve them all, and you will find that God's love has entered your heart strongly. You will lift your heart unto God that He may help you to serve them. Then you will give thanks to Him that He has given you what they need that you may give them.
