The church belonging to Christ, also known as the church of Christ, is bigger, more majestic, more awe inspiring than anything NASA will ever put on another planet. It was the only institution built by the Christ during His time on earth (Mat. 16:18), it is the only one made so that every person on earth that has or will ever live, if they wish to, can become a member of (Isa. 2:2, John 14:2). Not only will all people fit if they meet the requirements ordained by God for salvation (John 3:16, 2 The. 1:8-9), but the church of Christ is so beautiful that no one can every understand the complete beauty of this great thing given to us by God (Rev. 22:17ff).
Just as everyone should be behind this great endeavor to understand more about our universe, everyone should be searching for the greatest thing of all... God and His church. After all, it doesn't matter one bit if we ever learn about a mountain on another planet, or even if we pave the way for humans to visit that planet one day, if we lose our souls in the process (Mark 8:36). Do you want to know more about the church belonging to Christ? If so, just ask one of His people, Christians, those who follow the New Testament alone for their religious guidance and adhere to His commands (cf. Gal. 3:15-25, Jam. 1:27, Acts 11:26). If you ever want to know about a person or their house who better to ask than their friends (John 14:15)? One way you can do that is to click the "Contact Us" link at the top of your page. Jesus Christ said that if we will have curiosity about His way all we have to do is follow after Him and He will save us (Mat. 11:28-30, cf. Acts 4:12). And remember, we may seek answers to great questions on Mars but the thing we should be seeking first is the kingdom of God, His church (Mat. 6:33)!
