Ephesians 2:20 states

And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;

Therefore, Jesus Christ has left his witnesses and the word to follow.

There are questions and answers in the scriptures that teach to our souls.

In Acts 2:37-38

V37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?

V38 Then Peter said unto them, Repent, and be baptised everyone of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.

Obedience is better than sacrifice...
