Numbers 23:19 God is not a man, that He should lie; neither the son of man, that He should repent: hath He said, and shall He not do it? or hath He spoken, and shall He not make it good?

This scripture can speak for itself.
Whatever God told you in His written word or through the Holy Spirit, He will do. He’s not going to change His mind and He’s not going to renege on His promise. It’s already done, but it has to materialize in this physical world.

Whatever God said is not going to happen automatically or because we’re born-again. It’s going to happen because we used faith to obtain it. Faith is believing God’s word and acting on what we believe.

If we truly grasp the truth that God can’t lie, it makes it easier to believe and trust Him. Place your faith in God.
