The word "firm" is used several times in various translations of the New Testament. It is a word that refers to something that is constant and cannot be shaken. It refers to something that is sure and trusting. It refers to something that is so rigid and steadfast that it cannot be moved.
This term is applied to Christians in reference to their faithfulness to God.
Hebrews 3:6 says we are God's house if we hold fast our confidence and the boast of our hope "firm" until the end.
Hebrews 3:14 says -- "For we have become partakers of Christ, if we hold fast the beginning of our assurance firm until the end."
The Hebrew writer in Hebrews 10:23 indicates this firmness -- "Let us hold fast the confession of our hope without wavering, for He who promised is faithful."
And in 1 Corinthians 15:58 Paul writes -- "Therefore beloved brethren, be firm, immoveable, always abounding in the work of the Lord, knowing that your toil is not in vain in the Lord."
And in Colossians 1:23 -- "...continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel that you have heard...."
