Therefore He who supplies the Spirit to you and works miracles among you, does He do it by the works of the law, or by the hearing of faith?—just as Abraham “believed God, and it was accounted to him for righteousness.” Therefore know that only those who are of faith are sons of Abraham. Galatians 3:5-7
God spoke to Abraham and made a promise to Him by faith. Abraham believed God.

This covenant was actually made through Jesus without the knowledge of Abraham. Jesus told the Pharisees “Before Abraham was, I Am”.
If you are a believer, you are a descendant of Abraham and an heir to this covenant.
Faith comes by hearing and hearing by the Word of God. The foundation of a relationship with Jesus is built on hearing and accepting the Word of God by faith. There is no other way.
The promise of salvation can only come to you by faith. Without faith you cannot please God or live in His kingdom.
God supplies the Holy Spirit and performs miracles in your life by your faith in His promise to believers.
Many believers come to Jesus by faith and then quickly transition to works or religion to placate God. Faith gets lost in their pursuit to please God.
Your walk of faith will bring the promises of God into your life. No one is justified with God through works. There is no obligation from God for those who attempt to work for their salvation. God will only respond to your unyielding faith in His promises.
Abraham heard the voice of God calling him to leave his homeland. He gave up his security, inheritance, and protection to follow God by faith on an unknown journey.
The question is are you living by faith and following the voice of the Living God?
