Jesus came to bless us, not to curse us. But we must choose to receive that blessing and hand it on to others. Blessings and curses are always placed in front of us. We are free to choose. God says, Choose the blessings!
For further reflection...
Balak said to Balaam, "What have you done to me? I brought you to curse my enemies, but you have done nothing but bless them!" He answered, "Must I not speak what the Lord puts in my mouth?" - Numbers 23: 11, 12 (NIV)
