There is no true victory outside Jesus. You are an conqueror if you have Jesus as your formidable partner. Don't give up because you failed severally. Jesus is your burden bearer and capable of helping with all burdens and disappointments. If the greatest is in you, you will overcome all troubles. Deploy the use of the spiritual weapon made available to you: the Word, the Communion, the mystery of the Anointing oil etc. There are great rewards if you stand fast and firm, to watch over what God has given to you.
