No soul is held responsible for any actions that it is not capable of performing. Every soul reaps the effect of its own actions. This is the basic teaching of Islam. Allah also taught us that seeking and acquiring knowledge is the responsibility of a believer. So, while gaining more knowledge and thereby expanding the capabilities, we pursue the never ending path to success. In this sermon, Khalifatul Masih V went through this teaching in the light of explanation from the Promised Messiah (as).
We should understand that the responsibility on us is to put efforts as such as our soul can stand and try to progress in our knowledge. We cannot stay at one place saying that’s our limit. Promised Messiah says that a believer cannot stop at any level of his journey. If he stops, he gets under the influence of Satan and he will slowly drift away. Purification is a continuous process. The more knowledgeable one is, the more he sees Allah and follows the right path.
The Holy Prophet (sa) has been sent as a guidance for the mankind of all nations and all times. We should learn more from his life and follow his examples. We should also apply our intellect and reasoning, since intellect is a blessing from Allah.
