In John 14:1-14, Jesus comforts his disciples, assuring them not to be troubled and to have faith in God the Father and in Him as the Son. He speaks of preparing a place in heaven for them and emphasizes that He is the way, the truth, and the life, and that no one can come to the Father except through Him. Jesus also promises them that they will do great works and that their prayers will be answered, bringing glory to God.
