Matthew 17:19-20
19 Then the talmidim went to him privately and said, “Why couldn’t we drive it out?” 20 He said to them, “Because you have such little trust! Yes! I tell you that if you have trust as tiny as a mustard seed, you will be able to say to this mountain, ‘Move from here to there!’ and it will move; indeed, nothing will be impossible for you!”
Being included in the Kingdom of Heaven is simple, trust in Adonai. This doesn’t mean acknoledge He exists, but have a relationship with Him through prayer and studying His Word. We wonder why we have so much trouble in this life, for me it has been a lack of trust. God please continue to circumcise my heart and draw me closer to You, Amen.
