You therefore, my child, be strong in the grace that is in Christ Jesus. — 2 Timothy 2:1

"be strong in the grace that is in Christ Jesus" — not in yourself, but in grace. Be strengthened with all power according to his glorious might. Walk in Christ, rooted and built up in him. He gives a garment of praise for a faint spirit, and you're built on the foundation of Christ himself. He will complete what he started in you.
