Steve Camp has an excellent post on our responsibility to the body of Christ (...strengthening our commitment to the household of faith</i>).
The church is not merely one commitment to juggle along with all the others. Upon conversion God grafts his people into the body of Christ. God loves the church. Christ died for the church. The church is the community of people wherein my life takes on more and more Christ-likeness. The church is full of problems because she is full of sinners like me. But she is still Christ's beautiful bride. Jesus Himself is even now working to present her (us) before Himself holy, free of all blemishes.
