There blessings of the firstfruit offering to the giver are:

a. Diverse

The blessings of obeying God’s commandments are documented in Deuteronomy 28.  The reader immediately realizes that a multitude of diverse blessings come to those who take God at His word. 

b. Expect multiplication of that which was given, regardless of the size

Proverbs 3: 10 reminded Israel that the barns would be filled with plenty, and thy presses shall burst out with new wine when the firstfruit offering was given.  The widow of Zarepath got an increase in cornmeal and oil when she fed the prophet with the First and last cake which she had. Scriptures also abound in examples.

 God gave us His firstfruit, who was Jesus, and reaped the multiplied blessings of many sons and daughters (Heb 2: 13); many believers who will be resurrected from the dead (1 Cor 15: 20).

b. God defends you

Jeremiah 2: 3 says thatIsrael was holiness unto the LORD, and the firstfruits of his increase: all that devour him shall offend; evil shall come upon them, saith the LORD”  There is an inverse  principle here that relates to the protection that will be given to those who give the firstfruit offering, as shown also in Malachi 3.

d. The firstfruit brings forth another firstfruit

Scriptures teach us that God gives seed to the sower. When we sow again we are provided with other firstfruits. One beautiful example is that of Abraham who was promised that all nations would be blessed in his seed. He was asked to give the firstfruit of his son as a sacrifice, a type of Christ. God’s cancelling of that request shows that He did not really mean it/does not accept human sacrifice. As a result of Abraham’s faithfulness, God multiplied his offspring and Christ the firstborn among many brethren (Rom 8: 29).

e. What happens when a human is given as the firstfruit offering

The Israelites were commanded under the law to   give their firstfruit offering to the Lord:

Sanctify unto me all the firstborn, whatsoever openeth the womb among the children of Israel, both of man and of beast: it is mine (Ex 13: 2).

Hannah obeyed this command and gave her son Samuel back to God in a very literal manner. Isaac became the firstfruit offering to the Lord. Jesus was also a firstfruit offering.

The blessings of the firstfruit offering are the same regardless to whether or not it is human or material or otherwise.  I can testify to having been given as a firstfruit offering to the Lord (now that I think about it). God will use that offering to bless multiplied others in the same way in which He blessed Isaac, Samuel and Jesus.

I believe that every child should be presented to God as a firstfruit offering in order to reap the blessings.

Blessings until next time.
