I want answers!

Can anyone give me answers or a referral to someone who can explain me this?

Why there are people that have yauchts and there are people that they cannot afford a home?

Why there are families that cannot have children and a child of 15years old get pregnant?

Why babies born with cancers?

Why people born in a rich family and others born in a poor family?

Destiny is already planned by our Lord and Lord loves us equally.
