You will not find the word "membership" in the bible, but that does not mean the wise concept of membership is not present throughout the scriptures. You will also not find the word "trinity" in the bible, but that doesn't mean that the bible is silent on the matter of our triune God.
The concept of membership is a pastoral desire to be able to identify the people of God from within the Sunday morning crowd. Not everyone who shows up on Sundays is a believer, and we LOVE that that is the case. However, in order to best care for the flock that God has entrusted to us, we want to know who those people are that make up the church here at All Church. Membership is about identifying, equipping, and caring for the family of God that has been gathered at our local church.
Throughout the New Testament you see that the Lord "added to their number day by day..." implying that they were aware of who made up the church and who did not. All throughout the epistles we see that Paul wrote to the churches confident that they were "saints". At times there were those who evidenced themselves to not be christians and so he told the Corinthian church to remove that man from among them (1 Cor 5:1-2). How could he be formally removed unless he was formally recognized? The church knew who belonged to Christ and who did not. We too desire to have this awareness at All Church to be able to better care for everyone who attends our gatherings.
