We are not created by God for only ourselves alone. True responsibility is not looking out for just ourselves but others as well. We do not really possess any power of our own to do anything. Even the money we acquire is not as a result of our labour, it is by the grace and mercies of God.
Deuteronomy 8:18
But remember the Lord your God, for it is he who gives you the ability to produce wealth, and so confirms his covenant, which he swore to your ancestors, as it is today.
We require the power of God to produce wealth. It is wrong to boast of ourselves, strength or our hardwork for the reason of our success. It is God who gave us the enablement and He has the reason why He did so. Part of the reasons is so that we can reach out to the needs of people out there who are not as privileged as us.
Our Christianity is more of practical than is it is more of doing. It is also more about selflessness. When we start thinking of having concern for other people then we are getting the whole idea. When we have this understanding we would not hesitate to reach out to those that are in need of our help.
