The apostles and elders met to consider this question. 7 After much discussion, Peter got up and addressed them: “Brothers, you know that some time ago God made a choice among you that the Gentiles might hear from my lips the message of the gospel and believe. 8 God, who knows the heart, showed that he accepted them by giving the Holy Spirit to them, just as he did to us. 9 He did not discriminate between us and them, for he purified their hearts by faith. 10 Now then, why do you try to test God by putting on the necks of Gentiles a yoke that neither we nor our ancestors have been able to bear? 11 No! We believe it is through the grace of our Lord Jesus that we are saved, just as they are.”12 The whole assembly became silent as they listened to Barnabas and Paul telling about the signs and wonders God had done among the Gentiles through them. Acts 15:6-12
Have you ever seen that little gem that I highlighted tucked away in this passage? Sure, we know Eph. 2:8,9, Titus 3:5,6, and are familiar with Romans 3 & 4, but here is the gospel tucked away in the first church council as stated by Peter.
What is "grace". Unmerited favor is one definition. Another I like is getting what we don't deserve. The Jews were thinking, "The Gentiles don't deserve salvation because they aren't obeying the law, specifically circumcision". Peter would say, "Yes, you are right, they don't deserve salvation and neither do you because the law is a yoke that none of us can bear. All of us fall under the weight of the law."
Every religion in the world except true Christianity believes you earn your salvation. C.S. Lewis was asked, "What's the one thing that distinguishes Christianity from all other religions?" He thought for a second and replied, "Grace."
Islaam teaches heaven can be reached through practicing worship and doing good deeds and you'll find out in the end if you got there.
Judaism teaches obey the law and live a faithful life
Hindu teaches meditation, discipline, ethical conduct and Karma
Buddhism teaches follow the 8-fold path
I say "true Christianity" because Catholics believe we are saved by grace plus works. Mormons believe that to reach the highest heaven you must follow the temple ordinances. Jehovah Witnesses believe that to get to be one of the 144,000 you have to be obedient and faithful. Church of Christ believes you have to be baptized, and certain groups of Christians believe that you can lose your salvation which implies you are doing works to maintain it. Reformers go as far as saying that if you believe that your faith saved you then it's your effort that saved you - faith must be given by God, therefore only reformed Christians are saved. This goes against Paul's teaching in Romans 3:27&28 and Chapter 4 which distinguish faith from a work, but I'm getting off track.
So what is the gospel that Peter is preaching? Everyone likes to go back to what the earliest churches believed to prove their beliefs are right, so it doesn't get any earlier than this. Peter teaches in verse 9 that God purified their hearts by faith. What's that mean? Admit that your heart is dirty and trust in Christ's gift of forgiveness or cleansing done by his death on the cross as the only remedy for your sins. Then walk in that grace.
Someone on Twitter asked today, what song would you play if there was 5 minutes left till the Earth was destroyed by a meteor? For me it would have to be "The Grace by Which I Stand" by Keith Green. That is my only hope for the future. That and the fact that my parents circumcised me as a baby. Ha
