For many years I thought myself a Christian because believed in Jesus but I was an imposter missing the keys of the Kingdom.
The keys of the Kingdom
The who: Jesus is the son of the living God that takes away the sins of the world.
The what: Jesus died for our sins, was buried and rose again to life, seated at the right hand of God
The how: salvation is by the grace of God through faith in his son
The when: at baptism, salvation occurs when a believing, confessing, repentant sinner acts upon their understanding of the Gospel of Christ
The where: here and now. Do not delay, because salvation is at hand
