Here are some of the Spiritual habits I have added over the years that have proved to be a great benefit for me.
When I was a young Christian, still in high school, I invested in reading the Bible for fifteen minutes a day. This was the start of the a life long habit of Bible reading. Every year I have the satisfaction of completing another pass.
In college, I added the habit of scripture memory. First, I spent daily time memorizing new scripture verses. Eventually this transformed to keeping in review verses already memorized.
I have used “fifteen minutes a day” mentality to add other devotional habits that also increased my skill set. During Seminary, to maintain and increase my knowledge of Greek, I added the habit of daily reading the Greek New Testament. A few years after Seminary, I added the habit of reading in Hebrew. These habits have added depth and color to my Bible reading as well as strengthened my knowledge of Biblical languages.
I have tried various ways to sustain a daily prayer time. I have at various times tried prayer journeying, writing down prayer requests on cards and praying through them and taking prayer walks. The last few years, I make it a habit to pray daily, usually during a half an hour morning walk. Starting while we were dating and continuing into our married life, my wife and I pray together most nights. Just recently I skip two meals a weeks as a incipient effort at regular fasting.
While habits are not in themselves a devotional life, they provide times where devotion and connection with the Lord can take place. Starting from small beginnings, and over 40 years, my devotional habits have expanded from a short daily Bible reading to something that requires and significant investment of time each day. It has been well worth the investment.
