Country or exclusive clubs are usually restricted to a certain caliber of people. Such people must meet a certain criteria outlined by the club they wish to join and not everyone can be a part of it. Those who don’t meet the requirements are usually turned away when they wish to take part of the club benefits.
The Kingdom of God can be likened to an exclusive club; only those who believe, choose to accept Jesus Christ as their Lord and Savior and then confess his Lordship over their lives can belong to the kingdom of God [Romans 10:9-10]. But the truth is, once you become a member you have to live out our life like a member should. As a new member, you become the righteousness of God in Christ Jesus [Romans 3:22], dead to sin and alive in Christ and you are a holy nation and royal priesthood [1 Peter 2:9]. The new life you have gives you freedom but not to sin so that grace would abound [Romans 6].
The Kingdom of God requires that you go through the “narrow gate” [Matthew 7:13], take up your cross daily [Luke 9:23] and seek first the kingdom of God and his righteousness [Matthew 6:33]. As a member you are encouraged to flee from the lusts of the flesh and be filled with the fruits of the Holy Spirit [Galatians 5:22-23]. Above all, members are required to walk in God’s love which covers a multitude of sins and is the greatest of all things [1 Corinthians 13:4-13].
The kingdom of God has only one way into it and that is through believing in Jesus Christ as the Savior and Lord over your life. He is the only “way, truth and the life. No man comes to the father except through me” [John 14:6, NLT]. In the Kingdom of God, “But the gateway to life is very narrow and the road is difficult, and only a few ever find it” [Matthew 7:14, NLT]. But be rest assured that when you stand and live for Jesus here on earth, he will openly declare you to God the Father in heaven. Becoming a born-again Christian will cost you relationships, the worldly perception of success/wealth, life, time, energy and money. But remember that there is a crown of life waiting for you.
When all is said and done on that day of judgement, when you have fought that God fight of faith, you will hear “well done, ye good and faithful servant” [Matthew 5:21].
