Today I give thanks for all the good within my life. I am healthy, I have sufficiency in the things I need and God is always good.
Now, that does not mean that I do not have concerns, times of need, or times when I hurt because of issues within my life. I have times that I look back. I think about how I could have accomplished more, however being a Christian does not save us from life experiences.
We cannot undo the past, live it again, or do it over. I have to accept, move on, and depend on the Lord to take care of me now. This is what every human must remember.
I search daily to be more like Christ, more loving, more prayerful, be kinder, and more of all things, what he would have me to be. I often fail to be what I know he would have me be. I am not perfect, and I am not deceived into thinking I am. However, I do profess that I am striving to be more in his will, his commandments, and live a life of love for my fellow Christians, and all human life. I seek to understand more about myself and want to be able to seeking understanding of others, instead of judging, I try hard not to judge, and most of the time, I succeeded. I seek to live my life like someone who has the Spirit of God within.
"But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now, if any man have not the Spirit of Christ, he is none of his." Romans 8:9
This is plain English, and it is not referring to the Holy Ghost, this is the Spirit of God, that we receive when we become saved, and become a Christian.
More than likely the answer to that from some would be, because we are humans with humanly traits even though we are born of the spirit. That is somewhat clarified in the scripture also here:
"For he knoweth our frame; he remembereth that we are dust." Psalms 103:14
