Hebrews 12:1

Therefore, since we are surrounded by so great a cloud of witnesses (who by faith have testified to the truth of God’s absolute faithfulness), stripping off every unnecessary weight and the sin which so easily and cleverly entangles us, let us run with endurance and active persistence the weight which is before us. 

Is there something that is slowing down the spiritual progress in our life? If our focus is trapped by sin or lack of commitment, the growth will slow down or stop. We can’t be double-minded with the things of God; what we say to ourselves on the inside matters more than what we say to others on the outside.
