people are not efficient

"Spending time with other people is not very efficient! But God has a bigger and, quite frankly, messier and less efficient plan.
Being involved with people is time consuming, messy and complicated. from our point of view it is inefficient, but from God's point of view it is the best way to encourage growth in grace... That means we will have to make time for these kinds of friendships to emerge and grow. we will have to be realistic too. Close relationships make it more likely that you will sin against someone or that someone will sin against you."
