Ephesians 1:2

² May grace (God’s unmerited favor) and spiritual peace [which means peace with God and harmony, unity, and undisturbedness] be yours from God our Father and from the Lord Jesus Christ.

Notice where we are shown that Grace comes from, it is not from us, it is from our Father. Grace is underserved favor with God. We can do nothing to earn favor with God or obtain His favor. Grace is just given and it is given to us from God. Which leads me to what a lot of people believe and that is that Grace must be accepted to be had. But if that were true, then wouldn’t that mean that grace is earned by our acceptance? Yet we are plainly told that grace is unearned.

So that, [just] as sin has reigned in death, [so] grace (His unearned and undeserved favor) might reign also through righteousness (right standing with God) which issues in eternal life through Jesus Christ (the Messiah, the Anointed One) our Lord. Romans 5:21

Our Father is not a respecter of persons, Acts 10:34. So this must mean that Grace is freely given to everyone, even if they don’t accept it! Think about the Jews who crucified Jesus to see this glorious Truth. These guys had no excuse whatsoever. They knew the Scriptures. They had seen the dead raised, the lame walk, and the blind gain their sight. Even though they lied, tortured, and killed Jesus, they still received forgiveness and Grace, Luke 23:34. They did not ask for it and they did not believe that they had received it. Yet they still did, that is how awesome our Father is and that is how powerful Jesus’ sacrifice was. If it were up to us to accept Grace we would blow it.
