How can someone gain entry to the Kingdom of Heaven?

Gaining entry to the Kingdom of Heaven is not based on individual merit or righteousness, but solely through faith in Jesus Christ. As revealed in Matthew 7:21-23, mere religious observance or good works do not secure admission; rather, one must do the will of the Father, which involves trusting in Christ as the source of grace and salvation. Christians believe that Jesus, through His sacrificial death and resurrection, has borne the curse of the law to redeem His people. This is clearly illustrated in the case of the repentant thief on the cross (Luke 23:39-43), who simply looked to Jesus for salvation and received the promise of paradise. The call is for all to look unto Jesus and believe, as shown in Isaiah 45:22.
