Secret of entering into Kingdom of God

Those who are rendering service unto Him directly under the direction of His beloved agent are rendering service unto Him favorably. Such favorable servitors are devotees of the Lord, and by the grace of the Lord they can enter into the mysterious region of transcendence by the mercy of the Lord. 

But the mental speculators remain in darkness all the time. As stated in Bhagavad-gita, the Lord Himself guides the pure devotees toward the path of realization due to their constant engagement in the loving service of the Lord in spontaneous affection. That is the secret of entering into the kingdom of God. Fruitive activities and speculation are no qualifications for entering.
