From my calculations, the minimum number that should be added to any church yearly is 365. He added daily (365 days) Acts 2:47. However, your church/business will not grow beyond the level of unity or oneness within the church or business. It is not for lack of effort but the divisiveness in the midst thwarts the results that should be seen. Until all the working elements are in sync in the church (body) or business, growth is a pipe dream.
The Holy Spirit engenders growth. Everywhere He is there is explosion of favour which gives birth to increases in number/clients but they must be as it were in one accord and have all things in common. He can’t stay in a chaotic environment. The oil does not flow when brethren or workers are not united.
