The law was about Jesus, when Jesus came, he fulfilled it.
How was the law about Jesus? The law with the commandments was about Jesus and the ordinances that was given is the purification works in which one had to do to because the commandments were CONTAINED IN ORDINANCES are ALL about Jesus. The ORDINANCES were the PURIFICATION WORKS.
THE PURIFICATION WORKS WERE ABOUT CLEANING ONESELF, and NOW ONLY JESUS CLEANS US.
Jesus taught to BELIEVE IN HIM, HAVE FAITH IN HIM.
Have faith about what?
Believe that we have to obey Jesus now and have faith that HE CLEANS us of the sins we repent of doing.
It means we still have to obey God---we just don't have to observe special days, do various external baths, adhere, to a special diet, and get circumcised.
THOSE THINGS WERE NAILED TO THE CROSS BECAUSE JESUS TAUGHT BELIEVE IN HIM. BELIEVE IN HIM THAT HE CLEANS US NOW.
Colossians 2:14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
Colossians 2:20 If you have died with Christ to the spiritual forces of the world, why, as though you still belonged to the world, do you submit to its regulations:
Ephesians 2:15 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;
Jesus NOT abolishing the law means WE STILL HAVE TO BE CLEANED, PURIFIED, JUSTIFIED, WASHED...BUT NOT by the old law----by the new law which Jesus taught while he walked the earth.
I do not see anywhere where God did away with only the ceremonial law.
Jesus in fact commanded Israel to keep the whole law Matthew 23:2-3
In fact Ezekiel 40:41 says there will be sacrifices in the yet future millennial temple in the Davidic kingdom.
Regardless, Israel was to keep the commandments and baptism was one of them (Mark 16:16) so Ananias would be keeping the commandment to baptize believers.
