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
