You know...I get a lot of accusations and doubts thrown at me regarding who I really am in Christ.
One big step for Christian growth is learning to let Jesus be our foundation and not our senses or our feelings. Some days I act completely contrary to who I really am in Jesus Christ. And then the question comes of how I can really have the Spirit of God in me when I do such things or feel such things or think such things? Why would God give His Spirit to me? I don't do anything special or important.
The biggest step of faith is completely ignoring these feelings and doubts and acting as if we are the righteousness of God in Christ Jesus not because we feel it, sense it or act like it all the time. No...Faith is the assurance of things not seen. Faith counts it to be so not because it has evidence, but simply because God has promised and God is no man that He should lie. We walk by faith, not by sight. I take this to mean that we also do not walk by feelings, experiences or whatever senses our bodies may have. Let us mix this Gospel with faith! The Lord said blessed are those who have not seen and yet have believed!
Faith is, like Malcolm Smith has mentioned, not closing our eyes tightly saying "I believe, I believe, I believe." Faith is a rest and trust in God by keeping your eyes on Him. Faith isn't concerned with itself, but it's object. Those who were commended as having great faith in the Gospels were not conscious of their faith. They were conscious only of Jesus.
So let us fix our eyes on Him and not on ourselves. He will lead us and guide us and teach us. And this process will not be organized. It will be messy.
