Sometimes it is because we lag behind the Lord. At other times we impatiently run ahead of Him. And sometimes we actually turn away from the Lord. But in all cases, as different as the details might be, we get away from Him, and that is the cause of our failure–something we need to avoid at all cost. This is cause for serious thought.
Accepting Christ is the only way to salvation (John 14:6) and abiding in Christ is the only way to success (John 15:4-7). He who is our only hope of heaven is also our Helper until we get there, and help is something we all need–all the time. We are so very weak that without Him we can do nothing. That fact ought to humble us. In and of ourselves we have nothing of which to boast. The only good in any person is Christ. And for that we ought to be eternally thankful.
Let us then love Him with all our heart, serve Him with all our strength, glorify Him in all that we do, give to Him all our devotion, trust Him for all our needs, and find our pleasure in pleasing Him. Do these things and you will not fail. In the doing of these things we will be able to keep going and growing regardless of the circumstances.
