The Bible says that we should not forsake "our own assembling together, as is the habit of some, but encouraging one another; and all the more, as you see the day drawing near," (Heb. 10:25). It is wise to go to church because that is where we can go to hear the Word of God preached and to experience the friendship of other believers.
It is very important that we hear the Word of God. The Bible says, "So shall My word be which goes forth from My mouth. It shall not return to Me empty, without accomplishing what I desire, and without succeeding in the matter for which I sent it," (Isa. 55:11). Also, "For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart," (Heb. 4:12). The Word of God--when it is preached--presents to us the truth that the Lord wants us to know. We need to hear the Word of God presented to us, analyzed, and applied to our lives so that we can live better, accomplish what God desires for us, and can bring glory and honor to Him.
The other very good reason mentioned above for going to church is to experience friendship with other Christians. We need friends in order to be well balanced and healthy. Also, in church we discover opportunities to serve and be served. Therefore, we learn to apply what is taught out of God's Word, and then we learn to extend it to others outside the church.
Also, in church we share in the successes and failures of others and learn how the Lord has worked in the lives of other people. In this, we are encouraged. Remember, God did not make us to be alone. We need the friendship of other believers.
So, you should go to church because that is where you can hear the Word of God explained and applied to your life, see how God works in people's lives, and experience the friendship of others.
