Read the title of this blog post again. (I'm waiting...did you do it?).
That's right. You read it correctly. There is no organization on the face of the earth greater than the church of the Lord Jesus Christ.
It's founder is Jesus Himself. "And I tell you that you are Peter, and on this rock I will build my church..." Matthew 16:18
It was Jesus who gave His blood for the church. "Be shepherds of the church of God, which he bought with his own blood." Acts 20:28
He is the Head of the Church. "For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Savior." Ephesians 5: 23
Every church (no matter its size, location, or name) is equally important.
It is comprised of His saints on earth for a purpose. I Corinthians 1:2; Ephesians 1:1 - all addressed to the saints. Matthew 28: 18-20
According to Matthew 16: 16-19, it has been given the message that "even the gates of hell can not prevail against."
He is coming for His church - the bride. "Husbands, love your wives, just as Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless." Ephesians 5: 25-27
It's capabilities is not limited to the sum total of its faults, but instead is empowered by Jesus Himself through the power of the Holy Spirit.
Someone once said, "I'm surprised the church does as well as it does when you realize what it is comprised of." I'm the first one to acknowledge my weaknesses ("clay pot") and lack, but God still chooses to use the "weak things" to acknowledge His strengths and enhance His glory.
There is only one thing bigger and better and that is the Kingdom of God but it is internal and eternal. "Thy kingdom come, thy will be done."
