The heart who wants to please God will always seek to do those things that brings glory to God. Sin does not glorify God. Addiction is not something that is good. Though the word addiction by itself does not altogether mean something bad. One can be addicted to doing the things that are good. For instance if you are such a person who feels uncomfortable to leave someone who has a problem, that is a good addiction. I have seen someone who always sings. She loves singing songs of praises and worship. That is a good way to be addicted to something.
There are several things which we should be addicted to doing as christians. One of such is prayers. A christian should pray always. The Bible admonishes us to pray without ceasing. That is always pray. Do not stop praying for any reason. Another thing which we must always do and get addicted to is reading the Bible. Let us always read our Bible without getting tired. The Christan is someone who is on a pilgrimage. Without a guide, every pilgrim will miss his way. When we get ourselves stock in stock in reading our Bible, we are going to receive the right direction about our life.
So, what are you addicted to? Are you addicted to sinful habits like drunkenness, fornication, masturbation and others? If you are, get to the Word of God and open your heart for the word to cleanse and make you whole. You can start practicing what is good and allow good habits to overcome the evil ones in your life.
