Luke 6:38 (NKJV)

Give, and it will be given to you: good measure, pressed down, shaken together, and running over will be put into your bosom. For with the same measure that you use, it will be measured back to you.

Eisegesis: 

The more money you give the more you will receive. Your finances will overflow.

Exegesis:   

This verse is not about money rather it is about forgiveness.

This verse is often misused by some denominations that adhere to Word of Faith or Prosperity preaching, where it is employed to compel believers to give “seed money” or “faith money.” The underlying idea promoted is that the more one tithes or gives financially, the more blessings they can expect to receive from God.

But this verse has nothing to do with money.

To understand the context of Luke 6:38, we should back up a few verses to check the beginning of the context in Luke 6:35-36.

Luke 6:35-36 (NKJV)

But love your enemies, do good, and lend, hoping for nothing in return; and your reward will be great, and you will be sons of the Most High. For He is kind to the unthankful and evil.  Therefore be merciful, just as your Father also is merciful.

The context is clearly loving our enemies just as Christ loved us which translates into a powerful testimony for the gospel.

We should have a proper attitude in how we treat people, even the unbeliever, and verses 37 and 38 summarizes this principle adequately reminding us that we reap what we sow and in the amount in which we have sowed. If we judge others, we will ourselves be judged. If we forgive, we shall be forgiven, if we condemn, we shall be condemned (see Matt. 18:21-35).

We should note that this verse is not talking about eternal judgement but a return in how we are treated in this life.

In other words, “Be kind and gracious and loving, even to your enemies, and then even your enemies will want to be at peace with you.”

Lastly, since we are on the topic of giving, it is essential to understanding the New Testament’s standard for tithing in the Church; is to basically be a cheerful giver, rather than being compelled to give out of fear or with an expectation of receiving more;

2 Corinthians 9:7 (NKJV)

So let each one give as he purposes in his heart, not grudgingly or of necessity; for God loves a cheerful giver.
