Don't think you have committed a sin if you refused to give to people who are not doing something meaningful with their life. God is never cheating on them to bless you. The moment you feel guilty for having, people will use and manipulate you to their own selfish gains.
We will always thank God for his blessings. But the blessings of God does not come by being idle, it came on something meaningful that you were doing. And that same blessing is available for everyone.
You don't have to always feel guilty for another person's outcome. People choose what they will become. There are some specific seasons that people should do something with their life. When people are not serious and they will miss their season and begin to struggle for life.
If you have an opportunity to study and learn, please do it. Failing to learn and do something will make you poor. You don't have to feel guilty for what others refuse to do with their life. God sees. God rewards those who have decided to do something meaningful with their life. The blessings of God is available to all, but you must have something doing to tap those blessings.
What are you doing in your life that God can use it to bless you with.
