Under the Law, to receive a promise from God there was an “obey, then” clause. If we did our part (obeyed) then God did His part (bless).

Deuteronomy 28:1 “Now it shall come to pass, if you diligently obey the voice of the Lord your God, to observe carefully all His commandments which I command you today, that the Lord your God will set you high above all nations of the earth. (Also see Isaiah 1:19; Exo. 18:23)

Under grace, to receive the promises of God, we have a “believe, then” clause.

Matthew 21:22 If you believe, you will receive whatever you ask for in prayer.” (Also see Luke 8:50; John 14:12)

Although we’re under grace, a lot of people still have this “obey, then” mindset. They pray to God and believe for the promise (Matt. 21:22), but they will also fast, pray longer, and diligently read their bibles to get God to move on their behalf. It’s as if they’re working to receive a blessing. If we thoroughly read our roles under grace, we’re to ONLY believe. Believe in what? The finished works of Jesus.

Through Jesus’ sacrifice, all the promises of God have been made available for the taking (2 Cor. 1:20). Obedience to God is important, but it’s not the prerequisite to the promise. Once we’re confident the promise is ours and we’re patient, we’ll receive whatever we believe in due time. No works are needed. Receive every promise through belief.
