Understanding the intent and purpose of the book of Acts, in relation to everything else that is going on in redemptive history, is necessary to form a full picture of what God is doing in the world.
To separate the church into two separate entities, as hyperdispensationalism does; to reinsert the law (in part or in whole) into the New Covenant, as the Hebrew Roots movement does; or to say that the church has replaced Israel as replacement theology claims, blemishes the intent of what God is doing in the world.
Depending on the teaching, it can doctrinally destroy the effective working of Jesus Christ on behalf of all people, it can incorrectly consider other covenant promises made by God to the people of Israel, it diminishes the efficacy of the shed blood of Christ – marring or destroying the marvel of what God has done through His perfect life, sacrificial death in fulfilment of the law, and His resurrection.
Let us carefully pay attention to what Acts reveals. In doing so, we will avoid these false teachings and we will be able to hold fast to the wonder of the glorious gospel of Jesus Christ.
