We come to Christ as individuals; we each must make our own personal commitment to Him. We aren't saved because we belong to a group, but solely because as individuals we have put our faith and trust in Christ to save us.
But once we come to Christ, we become part of a family–the family of God. Think of it: You are no longer just an individual, but you are now part of a group–a spiritual "family" that includes every person on earth who truly believes in Jesus Christ. Everyone who believes in Christ is now your spiritual brother or sister! This family of believers is what the Bible calls the Church, the body of Christ: "Now you are the body of Christ, and each one of you is a part of it" (1 Corinthians 12:27).
Why is it important to be part of a local fellowship of believers? Let me ask you a question: What does God want to do in your life? The answer is this: He wants to make you more like Jesus. But this won't happen if you are isolated from other Christians. You need them–and they need you. The Bible says, "Let us consider how we may spur one another on toward love and good deeds" (Hebrews 10:24).
Ask God to give you a desire to become more like Christ. Then ask Him to help you find a church where you'll not only feel comfortable, but you'll find the fellowship and teaching you need.
