God's family consists of people from all nationalities, education, social status, and walks of life. The common denominator is that they are all lovers of Jesus who have been genuinely "Born Again" by the power of God.
As you become a part of a local body of Believers there are a few things to keep in mind. God's people are not perfect, they're being perfected just as you now are. It's not wise to look for perfection but rather look for sincerity of heart. You need to be among people who genuinely care about your spiritual well-being. You need to be among people who believe the Bible to be God's Word. You need to be among people who have a passion to live their lives in obedience to the Word of God and the local church you choose to fellowship with should be passionate about reaching the lost for Christ. Finding your place in a local church is not always the easiest thing to do, however, as you seek God's will in prayer He will direct your path.
1Cor. 12:14-27 - Yes, the body has many different parts, not just one part. 15 If the foot says, "I am not a part of the body because I am not a hand," that does not make it any less a part of the body. 16 And if the ear says, "I am not part of the body because I am not an eye," would that make it any less a part of the body? 17 If the whole body were an eye, how would you hear? Or if your whole body were an ear, how would you smell anything? 18 But our bodies have many parts, and God has put each part just where He wants it. 19 How strange a body would be if it had only one part! 20 Yes, there are many parts, but only one body. 21 The eye can never say to the hand, "I don't need you." The head can't say to the feet, "I don't need you." 22 In fact, some parts of the body that seem weakest and least important are actually the most necessary. 23 And the parts we regard as less honorable are those we clothe with the greatest care. So we carefully protect those parts that should not be seen, 24 while the more honorable parts do not require this special care. So God has put the body together such that extra honor and care are given to those parts that have less dignity. 25 This makes for harmony among the members, so that all the members care for each other. 26 If one part suffers, all the parts suffer with it, and if one part is honored, all the parts are glad. 27 All of you together are Christ's body, and each of you is a part of it.
