The biggest drain of our energy is unconfessed sin.
Psalms 32:3-5 When I kept silent about my sin, my body wasted away
Through my groaning all day long.
For day and night Your hand was heavy upon me;
My vitality was drained away as with the fever heat of summer.
I acknowledged my sin to You,
And my iniquity I did not hide;
I said, “I will confess my transgressions to the Lord”;
And You forgave the guilt of my sin.
We all sin, and God will forgive us our sin, but He requires that we confess to Him that we have sinned, that we own what we did. We don’t confess that we have sinned easily. We naturally protect ourselves from shame, and our inclination is to cover up our sin, to ignore it, justify it, and blame others. The energy loss that comes from unconfessed sin is not psychological, it is supernatural. God drains away our strength not because we have sinned but because we ignore our sin.
Along with our reluctance to confess our own sin is the problem that we have in forgiving others quickly for their sins against us. If we do not forgive others then God will not forgive us of our sins even if we confess them.
Matthew 6:14-15 For if you forgive others for their transgressions, your heavenly Father will also forgive you. But if you do not forgive others, then your Father will not forgive your transgressions.
There are a lot of very weary people in churches today trying to figure out what is the problem, why they are so tired all of the time.
Every night I take a few minutes and review the day and confess all my known sins to God. I usually do this in my journal so as not to take the process lightly. I also declare to God that I have personally forgiven everybody who has hurt me, violated my rights, and sinned against me. I declare to God that I am choosing to forgive because He first forgave me. If a person’s sin against me comes back into my thinking I forgive them again, and I keep on forgiving until the event no longer pops into my head.
Self-examination and confession of sin doesn’t take that much time at the end of a day, and it should be a daily spiritual discipline if we want to have God’s strength and energy filling us full all day long.
