Every follower of Jesus struggles with consistency. The reason is obvious, there is a lot fighting against our faith in Christ. The world as a whole regards Jesus Christ as a fairytale, and those who profess to follow him as idiots. The devil and his demons are constantly, 24/7, talking to us, resulting in thoughts of doubt regarding all we have heard and learned about Jesus and the Christian life. Our own sin nature is anti-faith, anti-god, and anti-supernatural. The New Testament is constantly exhorting and encouraging consistency, endurance, and perseverance so as not to backside or become lukewarm in our faith, because so many do.
Colossians 1:23 if indeed you continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel that you have heard.
There seem to be seasons of backsliding, and one of them is summertime. For some reason, many think that while on vacation, they can skip reading their Bibles, skip their time with God in prayer, skip attending church, and skip any times of self-examination, reflective thinking, and confession of sin.
It doesn’t take long living in a chosen state of lukewarmness to be locked in there permanently. The thought that we can easily backside and then be incapable of reversing our state of uselessness to God ought to create a fear that would motivate us to persevere in our Christian disciplines. But, no, most think it is no big deal; they can jump back into living the Christian life when September gets here easily, and with no problems. Those who think so are naive at best and fools at worst.
