When the ruler asked Jesus what he must do to inherit eternal life, Jesus replied that he must forsake all to follow after Him (Luke 18:18-30). If truly following after the Lord, we should consider all our time, talent, money, influence, etc…as belonging to God. It is up to us as stewards of that which now rightly belongs to God to use these various 'talents' wisely in his service (Mat. 25:14-30).
Forsaking all, however, does not mean that God wishes us to sacrifice things which rightly belongs to others. If we have a spouse, children or other family that depends on us for their daily needs, it would be wrong to not provide things needful for their health and welfare (1 Tim. 5:8).
