"But exhort one another daily, while it is called today; lest any of you be hardened through the deceitfulness of sin" (Heb. 3:13).
Hebrews 3:13 is an excellent Biblical description of what it is like to recognize our need for one another. It says very plainly to exhort one another daily. The Greek word here for exhort is "parakaleo", which means to call near to one's side. We need to come alongside one another very frequently--even daily--so that we don't get deceived and hardened by sin! I am not advocating daily "church services". I am simply suggesting that brothers and sisters have a lifestyle that includes one another. I'm simply suggesting that we recognize our need for each other and live accordingly.
We should be coming alongside one another very frequently for the purpose of spurring each other on in the faith. Notice: if we are aware of the possibility of being hardened by sin's deceitfulness, we will come together for a specific purpose. Our purpose will be to help one another to become more and more like Christ. Our purpose will be to help one another to do God's will and to increase in love (Heb. 10:24-25). We won't merely be getting together like a social club, without a higher purpose. No, our mission is clear and we will have great determination.
Contrast what I have just said with the way that most Christians live. For example, most church-goers see each other only at "official" church functions such as worship services, prayer meetings, Bible studies, picnics, etc. There are some who may "get together" with church friends outside of church functions. But many times such "get-togethers" are not very focussed; maybe a lunch get-together or an evening out, there is not often a determination, a purpose of sharpening each other to become more like Jesus.
Ask yourself: do your relationships with your church friends center around a mutual desire to help each other become more like Christ? When you get together with friends from church, how deep does it really go?
