Ezra 10:4 NKJV “Arise, for this matter is your responsibility. We also are with you. Be of good courage, and do it.”
Either of these two things will happen if you don’t do what you are supposed to do: it will wait for you or God will get someone else to do it. But if God has assigned a specific task to you, I encourage you to do it that you might be blessed.
Some people are saddled with certain responsibilities and they ignore it! That’s not the attitude of a Christian. As believers, we must endeavour to do well whatever we have been asked to do. Ecclesiastes 9:10 says “Whatever your hand finds to do, do it with your might; for there is no work or device or knowledge or wisdom in the grave where you are going.”
Inasmuch as it is good to delegate, you will only be robbing yourself of your blessings if you keep delegating to others what God has asked you to do yourself. Be bold, be strong, persist, and do whatever needs to be done when it needs to be done. God’s grace is sufficient for you.
