وَالَّذِينَ جَاهَدُوا فِينَا لَنَهْدِيَنَّهُمْ سُبُلَنَا (And those who strive in Our way We will certainly take them to Our paths — Al-Ankabut 29:69 ⧉). The real meaning of jihad is to put in all efforts to remove the hurdles in the way of faith. These hurdles include those that are put up by the infidels, for which fighting is at the top pedestal, and also those hurdles that are created by one's own Self and by Shaitan.
There is a promise in this verse Al-Ankabut 29:69 ⧉ for both types of jihad, that Allah Ta’ ala guides those waging jihad to the righteous way. It means that when there is a 'confusion between evil and virtue, truth and false, and profit or loss, and a wise person wonders which way to adopt, on such occasions Allah Ta’ ala guides those striving in His way to the path which is straight, righteous and without risk. In other words, He turns their hearts toward a way that may bring the divine blessing and the best results.
Knowledge improves if it is acted upon
Sayyidna Abu Ad-Darda' ؓ while interpreting this verse Al-Ankabut 29:69 ⧉ has said that the people who strive for acting in accordance with their knowledge are promised by Allah Ta’ ala in this verse Al-Ankabut 29:69 ⧉ that He will disclose to them some other areas of knowledge that they did not have before. Fudayl Ibn ` Iyad (رح) has given yet another interpretation to this verse Al-Ankabut 29:69 ⧉, that is, ` those who strive for knowledge, We make it easy for them to act'. (Mazhari). وَاللہُ سبحانَہُ و تعالیٰ اَعلَم
