John 14:26, NIV
Jesus never leaves us alone. He sent the Holy Spirit to teach and remind us what to do when we go through trials and storms. He will be there to give us the instructions and strength that we need. So if you feel so weak and you no longer have the courage to pursue the purpose that God planted in your heart, then call upon the Holy Spirit. He will give you extraordinary strength. He will lead you to the path that He prepared. Rely on Him and not on your strength. You will feel so alone if you just face the obstacles on your own. Remind yourself that Jesus gave you the advocate. He is there to sustain you until the end.
May you always feel the Holy Spirit in your life.
