-- Answer: "FAITH" and "BAPTISM" --

Just as Jesus said in Mark 16:16 that "He that believeth and is baptized shall be saved," Paul is showing the same need for faith and baptism in Galatians 3:26,27.

It's interesting to note all the wonderful things the Bible has to say about being "in Christ." For example, "There is therefore now no condemnation for those who are in Christ Jesus" (Rom. 8:1); "redemption" is "in Christ" (Rom. 3:24); one is "alive to God in Christ Jesus" (Rom. 6:11); "eternal life" is "in Christ" (Rom. 6:23); and there are many other verses as well, along this line.

And here in Galatians 3:26,27, one learns the answer as to how a person can get "into" Christ for all these blessings; and it is through faith and baptism.
