Romans 8:23
And not just the world, but even we [Christians] ourselves, who have the firstfruits of the Holy Spirit [i.e., the first installment of our inheritance from God] also groan within us, eagerly waiting to be adopted as [God's] children, and receive back our bodies [i.e., in the resurrection].
Romans 11:16
And if the first part of the dough is dedicated to God, the entire batch of dough will be also. And if the roots [of a tree] are dedicated to God, the branches will be also.
Romans 16:5
I also send greetings to the church that meets in their house. Greetings to my dear friend Epenetus, who was the first convert to Christ in Asia [Note: This was a province in the western part of present-day Turkey].
1 Corinthians 15:20
But now Christ has been raised up from the dead; [He is] the firstfruits of those who have died. [Note: By "firstfruits" is meant the first installment of the crop which promises the entire harvest eventually].
1 Corinthians 15:23
But each one [is raised up] in his own turn: Christ as the firstfruits [See verse 20]; then those who are Christ's [i.e., believers], when He returns.
1 Corinthians 16:2
On every first day of the week [i.e., at the regular Sunday assembly] each one of you should set aside and store up [money] in proportion to your income, so that no collections will have to be taken when I come.
James 1:18
It was God's purpose to bring us into being [spiritually] by the message of truth, so that we could become a kind of "firstfruits" of those He created. [Note: "Firstfruits" here suggests either that Christians are the best of all of God's creatures (Num. 18:12), or that they were the first to be converted, with many more to come].
Revelation 14:4
These people are the ones who did not practice sexual immorality with women, for they were virgins [Note: This probably has reference to people who avoided idolatry]. These are people who followed the Lamb wherever He went. They were purchased from among mankind to be the firstfruits [devoted] to God and to the Lamb.
