I can do all things through Christ who strengthens me.
Philippians 4:13 NKJV
“But I rejoiced in the Lord greatly, that now at the last your care of me hath flourished again; wherein ye were also careful, but ye lacked opportunity. Not that I speak in respect of want: for I have learned, in whatsoever state I am, therewith to be content. I know both how to be abased, and I know how to abound: every where and in all things I am instructed both to be full and to be hungry, both to abound and to suffer need. I can do all things through Christ which strengtheneth me.”
Philippians 4:10-13 KJV
This refers to Paul’s ability to be content in all things. To achieve this contentment, he needed the strength of Jesus Christ.
This does not mean God will bless whatever a person does. It means God gives believers the strength to do whatever he asks them to do.
I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing.
John 15:5 NKJV
