You all convinced me, I'm now an Atheist!!!

So your actions on earth, however moral or otherwise, are meaningless unless you give God your heart?

I've said this many times. The acts themselves hold no 'moral value.' It is what God says about then that gives them a 'moral or immoral' meaning.

Therefore it is only with the heart that we can serve God.

Again Look at the parable of the Rich young ruler:
The Rich Young Ruler

17 As He was setting out on a journey, a man ran up to Him and knelt before Him, and asked Him, “Good Teacher, what shall I do to inherit eternal life?” 18 And Jesus said to him, “Why do you call Me good? No one is good except God alone. 19 You know the commandments, ‘Do not murder, Do not commit adultery, Do not steal, Do not bear false witness, Do not defraud, Honor your father and mother.’” 20 And he said to Him, “Teacher, I have kept all these things from my youth up.” 21 Looking at him, Jesus felt a love for him and said to him, “One thing you lack: go and sell all you possess and give to the poor, and you will have treasure in heaven; and come, follow Me.” 22 But at these words [a]he was saddened, and he went away grieving, for he was one who owned much property.

23 And Jesus, looking around, *said to His disciples, “How hard it will be for those who are wealthy to enter the kingdom of God!” 24 The disciples were amazed at His words. But Jesus *answered again and *said to them, “Children, how hard it is to enter the kingdom of God! 25 It is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God.” 26 They were even more astonished and said to Him, “[b]Then who can be saved?” 27 Looking at them, Jesus *said, “With people it is impossible, but not with God; for all things are possible with God.”

Look at all the 'Moral' things this young man has done... They amounted to nothing because his heart was with his money/possessions.

A simple "yes" would've sufficed.
