Hope for the backslider!
Background: Last Sabbath I was asked to say something about my after baptismal life and my response was that, life got harder spiritually. Being Christian is a serious commitment, it hasn't been a smooth road for me, sometimes I often wish I hadn't received as much light as I have now. It gets tough! But as is with the rule of Mathematics; 'if it seems easy, you are probably doing something wrong.' The devil has no business with those who are already his, he doubles his efforts towards those in the other camp, those playing on the fence #LUKEWARM (as is the case with many of us).
How it all starts... The moment one shifts their attention from others to self. You start noticing the things that you don't have. Your prayers seem to be taking longer than usual to get answered. You get discouraged. You start throwing tantrums at God - you loose interest in personal devotion and prayers get shorter and shorter until you cease praying at all. Because the mind lacks spiritual matters to meditate upon, you spend much time thinking of all those things that don't seem to be going as you would have hoped. The negative aspects of life seem more attractive for some awkward reason. You are led to ponder more on your past mistakes which eventually leads one to conclude they are beyond repair.
Hang in there, Jesus will soon be here!
