Daily we evaluate our lives, reviewing what we've thought, said, and done. We consider the good things and the bad ... and we should! It's absolutely necessary to reflect upon our thoughts, words, and actions so we can repent of those that do not reflect the One who died to give us everything! God calls us to be holy, as He is holy (1 Peter 1:15-16). That means set apart from the world and it's standards, and living according to God's truth and His will and ways. Reflecting on our works and evaluating ourselves is a good thing, but we must be mindful that it is not for the purpose of defining our worth. When we have a good day, God does not love us more. And when we have a bad day, He does not love us less. Our value in His eyes is not based on our performance, or our good or bad "works." It is based on Jesus' work for us. Because Jesus took our sins upon Himself and died to pay the penalty for them, man can be forgiven by God. Because He rose again, conquering death, man can live eternally with Him. It is a free gift, given by God to all who repent and trust in Jesus and His atoning death for one's sins. That is GRACE — God's Riches at Christ's Expense.
When we take daily stock of our lives, remember that as blood-bought, Holy Spirit in-dwelt Christians, every sin we have committed is already paid for by Jesus. Our purpose and need in confessing daily sins is that we might repent of them. That means we are to turn from them and not continue to commit the sin or a similar one. We are to be growing in Christ:
"That we henceforth be no more children.... But speaking the truth in love, may grow up into [Christ] in all things..." (Ephesians 4:14-15).
Romans 8:29 tells us that we are being conformed to the image of Jesus. Let us mortify/crucify our daily sins through confession and repentance so we will more fully reflect His light in a dark world.
