Have you ever felt useless? Many times we don’t have materials sufficient to the task. We may not have the expertise for the job before us. God wants us to be humble, He wants us to realize that we are not sufficient to any task on our own. It is God which makes us sufficient.
2 Corinthians 3:5 says, "Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;" In this passage we see Paul telling the Corinthians, first of all to realize they are not sufficient to do anything. Despite all our skills and accomplishments we are not sufficient to live the life God has called us to. If knew only that, we would be hopeless. Thankfully we are not left in that condition. We are not hopeless; God is the one who makes us sufficient.
So I would like to encourage you, don’t look to yourself. You are not sufficient to live the Christian walk. No matter what the task is before you, humble yourself, and look to God. Trust in His sufficiency, and He will make you and shape you until you are capable for the work that He has called you to.
"Being confident of this very thing, that he which hath begun a good work in you will perform [it] until the day of Jesus Christ:" – Philippians 1:6
