While the principle of the tithe is still in place, Jesus was more concerned with the heart posture when we give. Life gets crazy, and yes Gods blessing is still waiting on you. But God is more concerned with where you heart is at rather than the size of the gift. Its all about the heart posture of Joy when we give.
2 Corinthians 9:7: Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
