12 Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned— 13 for sin indeed was in the world before the law was given, but sin is not counted where there is no law. 14 Yet death reigned from Adam to Moses, even over those whose sinning was not like the transgression of Adam, who was a type of the one who was to come. 15 But the free gift is not like the trespass. For if many died through one man's trespass, much more have the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many. 16 And the free gift is not like the result of that one man's sin. For the judgment following one trespass brought condemnation, but the free gift following many trespasses brought justification. 17 For if, because of one man's trespass, death reigned through that one man, much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ. 18 Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men. 19 For as by the one man's disobedience the many were made sinners, so by the one man's obedience the many will be made righteous. 20 Now the law came in to increase the trespass, but where sin increased, grace abounded all the more, - Romans 5:12-20
Blessings and curses are spiritual ramifications that manifest in the natural.
“And if you faithfully obey the voice of the Lord your God, being careful to do all his commandments that I command you today, the Lord your God will set you high above all the nations of the earth. 2 And all these blessings shall come upon you and overtake you, if you obey the voice of the Lord your God. - Deuteronomy 28:1-2
15 “But if you will not obey the voice of the Lord your God or be careful to do all his commandments and his statutes that I command you today, then all these curses shall come upon you and overtake you. Deuteronomy 28:15
Blessings and curses are generationally transferrable.
19 “Yet you say, ‘Why should not the son suffer for the iniquity of the father?’ When the son has done what is just and right, and has been careful to observe all my statutes, he shall surely live. 20 The soul who sins shall die. The son shall not suffer for the iniquity of the father, nor the father suffer for the iniquity of the son. The righteousness of the righteous shall be upon himself, and the wickedness of the wicked shall be upon himself. Ezekiel 18:19-20
Jesus took our curses so that we can be blessed
13 Christ redeemed us from the curse of the law by becoming a curse for us—for it is written, “Cursed is everyone who is hanged on a tree”— 14 so that in Christ Jesus the blessing of Abraham might come to the Gentiles, so that we might receive the promised Spirit[a] through faith.
