It does happen sometimes after i do my Christian routines perhaps you too that i or we feel bored. So what do we do ? in this case, I prayed Lord i am bored, help me. A thought then came to me to watch Christian programs on TV. I tried a few stations and surfed through them and even watched some wholesome secular shows.
This reminds me of an story of King David in II Samuel 11:1And it came to pass...at the time when kings go forth to battle....but David tarried still at Jerusalem ( perhaps bored ). The rest of the story tells about David's encounter with Bathsheba where David committed his sin.
The lesson here is being bored could present us with awkward position that lead to sin and so the first defense is to pray.
So when we do not know what to do, pray. This is better than having to look for something exciting for ourselves. Again the key is to pray.
