Anytime you see an “if you do this, God will do this” in scripture you are seeing Old Covenant. However, when you see that God has provided something and you and I are to simply respond in faith that is the New Covenant. The Old Covenant was based upon what you did and the New Covenant is based upon what God did for you. For example people often teach that if you give, God will give back to you (see Luke 6:38). The New Covenant reality is that God has already given and we can give because we are blessed. You see, verses like Luke 6:38 took place before Jesus went to the cross hence they were dealing with people who were not yet born again. Giving is your nature as a child of God. This is why it is important to know your identity in HIM. You are blessed.
