It means walking by faith.
For you have now put on the new person with your trust and commitment and devotion into a Person that you cannot see with your two eyes but can see inwardly with your heart, in a Voice you cannot hear audibly with your two ears but can understand inwardly with your soul, in a Presence you cannot touch, but whose movements you can detect with your mind. It is a relationship with the Set Apart Spirit whose goodness, grace and glory proves a unity with the Heavenly Father in every moment.
A second step in the faith comes after repentance, confession and the supernatural saturation of the Set Apart Spirit into your soul. You have been 'christened' with the love and wisdom and power of the Heavenly Father. Your inner eye is now washed clean, you are sanctified and your faith has made you whole. An outward sign or act of verification of this supernatural condition of replacing the old natural man with the new spirit-filled man is the act of baptism, a public confession of faith.
From here on your faith can take on many forms depending on the spiritual gifts granted to you by Our Loving Heavenly Father. Becoming a dedicated disciple of Yeshua Emmanuel, the Christ is a surefire way of keeping your life connected to Heaven by the spiritual perseverance and development you will obtain. Becoming a disciple is means you have embarked on a journey and feel the powerful wind of Ruach ha qa dosh on your back to steer you forward. It means it is time to come out of hiding and proclaim His goodness. Yeshua says 'do not be afraid.'
Your penance is over.
He has guided you to this point in preparation because you have submitted inwardly in a ready devotion to His Word.
But being a disciple also means surrendering daily to a cause greater than yourself which is the cause of righteousness.
But Relax! To be righteous does not mean to be perfect. Remember you are a work in progress after the Will of Yeshua. Our Heavenly Father does not expect perfection. What He looks for in the heart to determine righteousness is not what man in the world looks for.
Do not focus on performing deeds. Study the Word of Yeshua, meditate on His Wisdom, seek Him with prayer. Stay centered in His Light of Life by eating, drinking and breathing His Bread, His Water, His Word, His Light!
It means walking by faith. Faith means being clear about what you regard as truth. And because you are clear inwardly about that truth you walk as if it is so.
And others seeing the evidence thereof in your life will give glory to the Father.
