Be devoted to your calling or vocation.
Your calling is your reason for living.
Therefore, no room for slack.
You must encourage yourself in your darkest night just like David did.
The passion for your calling and your purpose in life would be enough to reinvigorate your spirit and give you energy for another day.
And when things go not the way you plan them, remain strong. Be confident in the ability of God to keep you and help you.
Your confidence in God is your hope that God cannot fail.
Continually talk to God about everything.
Continue to say all of your minds to Him.
Don’t relent! Don’t give up!
Rom 12:12 Rejoice in hope, endure in suffering, persist in prayer.
