All of us have needs. Fear says,"No one is going to provide for your needs. You are a needy person with no one who can help." Faith says, My God shall supply all of my need according to His riches in glory by Christ Jesus (Philippians 4:19).
Our greatest need is not physical nor financial. Our greatest need is spiritual. We need God. We need faith in God who provides. God's covenant name among others is Jehovah-jireh. It means the Lord will provide. His name reveals His character. It's who He is and what He does.
God is Jehovah-jireh for His people. He is the Lord who provides for all who believe in His name. That means faith can trust in who God is. It's not just who we want Him to be. He reveals His name to you and all believers. We can trust in His name, receiving from Him according to our need.
God will provide as our heavenly Father. He knows our needs before we ask. Prayer is not designed for us to inform God. He knows all things. Our prayers receive from God our Father. Jesus said to pray, Our Father in heaven (Matthew 6:9). He taught us to make requests based upon our needs. Give us this day our daily bread (Matthew 6:11). God will provide as our Father in heaven.
