Our main determined purpose should be to know Christ [only] and considering all material possessions as mere rubbish. To know Him through sufferings and even to die a death like His.
For cursed with great evil is one who trusts in (relies on) man. The Word teaches us to walk according to the ways of the Lord. God is looking for us to have His thoughts and ways. Hence we need to make use of every opportunity and redeeming the times.
