To keep your balance on a bike, you need to keep pedaling. You need to move forwards. Unless you put your feet on the ground, you will wobble and crash to the ground if you stop pedaling.
And it's the same with the Christian life. We need to be always moving forward. Not necessarily always busy. Rest times are important. But always moving forward in our relationship with God. We need to keep praying, reading our Bibles, learning, obeying, trusting, applying, and so on.
That's how you keep your balance as a Christian!
In the Bible the Christian life is compared to a walk. Enoch walked with God. When you walk, you keep moving forward one step at a time.
Just keep plodding along!
Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.
But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To him be glory both now and for ever. Amen. 2 Peter 3:17-18
