1. God loves us - no matter how ugly the lives we've choose right now we cannot decrease the love that God has for us. He will always remain loyal and faithful to us.
2. Life is a gift - life is beautiful, it is a gift coming from a genuinely in love God and He expects us to develop an intimate relationship with Him. He expects men to be satisfied of that.
3. Many people love us - Although God's love is enough, He still provides bonuses, which is the love from the people around us. You might be discourage of the people who are indifferent, unreal or who ignore you but be grateful for the people who truly care and love you are too many to count.
There are more reasons why we ought to live but those three were the top three reasons why my life here on earth is so meaningful and beautiful.
