There is always something sad about Christians isolating themselves from the church fellowship in order to deal with their problems. Paul exhorts the Galatians and us to Carry each other’s burdens, and in this way you will fulfil the law of Christ (Gal. 6:2). This was demonstrated ongoingly in how the first church in Jerusalem committed their lives to each other (see Acts 2:42-47). Moreover Malachi tells us of those who feared the Lord talked with each other, and the Lord listened and heard. A scroll of remembrance was written in his presence concerning those who feared the Lord and honoured his name (Mal. 3:16). God loves it when His people are together.
To isolate from the fellowship is to cut yourself off from your God-given life-support system. These brothers and sisters have been given to you so as to be there for you. Going through personal difficulties with the church is beneficial to the church and to you. For the church, it shows the reality of the church ministering to each member of the body. When you come through, the church rejoices at how God has worked. Relationships are strengthened. The church also learns about the ways of God together as His Word works out in lives. For you it means that you have known that God through His people works to bring resolution and blessing into your life.
If you have happened to resolve your problems by isolating yourself from the church you harm the church and yourself. The church has not had the blessing of providing help. You as an individual have laid a basis for spiritual harm in the future. You think – “I got through on my own last time, I will do the same again”, Satan is happy, and others whether it be friends or family look on and see that the church is redundant. They are influenced away from the church.
