What does the Bible say about Christ being all we need?

The Bible clearly indicates that Christ is all we need, as He is our justification, righteousness, and sanctification. In Isaiah 10:20, it is stated that the remnant will not put their trust in anything other than the Lord. The assurance we have is that all we need for salvation is found in Christ alone. This profound truth is intertwined with the concept of total reliance on Him, as expressed in passages such as Romans 11:5-6, which emphasizes that salvation is by grace, not by works. As believers, we are called to lean solely on Christ for our spiritual needs, echoing the words in Galatians 2:20, where Paul declares that he lives by faith in the Son of God.
