The New Testament unabashedly offers rewards for certain forms of conduct. Heaven as a reward for virtuous behavior is a non-Jewish concept borrowed from Zoroastrianism along with dualistic cosmology.

Mt 5:1 And seeing the multitudes, he went up into a mountain: and when he was set, his disciples came unto him: 5:2 And he opened his mouth, and taught them, saying, 5:3 Blessed are the poor in spirit: for theirs is the kingdom of heaven. 5:4 Blessed are they that mourn: for they shall be comforted. 5:5 Blessed are the meek: for they shall inherit the earth. 5:6 Blessed are they which do hunger and thirst after righteousness: for they shall be filled. 5:7 Blessed are the merciful: for they shall obtain mercy. 5:8 Blessed are the pure in heart: for they shall see God. 5:9 Blessed are the peacemakers: for they shall be called the children of God. 5:10 Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven. 5:11 Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake. 5:12 Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.
