Matthew 26:69 Now Peter was sitting outside in the courtyard. And a servant girl came up to him and said, “You also were with Jesus the Galilean.” But he denied it before them all, saying, “I do not know what you mean.” And when he went out to the entrance, another servant girl saw him, and she said to the bystanders, “This man was with Jesus of Nazareth.” And again he denied it with an oath: “I do not know the man.” After a little while the bystanders came up and said to Peter, “Certainly you too are one of them, for your accent betrays you.” Then he began to invoke a curse on himself and to swear, “I do not know the man.” And immediately the rooster crowed. And Peter remembered the saying of Jesus, “Before the rooster crows, you will deny me three times.” And he went out and wept bitterly.
Romans 7:18-20 For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out. For I do not do the good I want, but the evil I do not want is what I keep on doing. Now if I do what I do not want, it is no longer I who do it, but sin that dwells within me.
1 Peter 1:3 Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, who by God’s power are being guarded through faith for a salvation ready to be revealed in the last time. In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, so that the tested genuineness of your faith—more precious than gold that perishes though it is tested by fire—may be found to result in praise and glory and honor at the revelation of Jesus Christ.
What can a person do when they have intentionally chosen to do that which they have said they would not? Some may deny the act or give it no thought. Its significance of it to them is like a passing of a gust of wind, they felt it but give it no thought. They may even give an excuse for it – I had no choice, I was just following the crowd, it wasn’t my idea, it really isn’t that bad, It didn’t adversely affect anyone else, no one saw me do it, etc…….. People like this may come to a place where they are sorry but never come to a place where they repent.
There are then those who become aware of the fact that they did exactly what they said they would not. Their heart is ripped in two and their sorrow is soul deep. Oh, that we would have hearts so tender as to be broken easily for the sins we commit. How sad is it if you are not aware of the sins you are committing? If our sole purpose in this life on this side of eternity is to honor and glorify Jesus Christ, then being aware of how we may be falling short would be a good thing to know and repent of. Having a tender heart that is open at all times to the leading and correcting Spirit of God will always lead us down paths of growth, maturity, grace, love, mercy, knowledge, wisdom, and understanding – And yes, it will lead us down paths of repentance if we would.
Our strength is not in ourselves but in the power of the Holy Spirit.
