Yes, we need confidence in God to walk in faith, to please God. Walk in love and you walk in grace and in the abiding presence of our Lord. He said that He would send us the comforter, and teach us all things. Lord wants to lead us into the blessing and promises of God. We just got to learn to trust him and obey, follow the voice the prompting of God, and you will begin to see your life turn around and the blessing of God upon your door.
2 Timothy 1:7
For the Spirit God gave us does not make us timid, but gives us power, love and self-discipline.
