Faith is the assurance that God will do exactly what He promised. Faith is the victory that overcomes the world.
Faith isn’t some button we push to force God into doing what we want. Many have prayed for things they wanted or thought they needed and their requests were denied. Sometimes they get bitter about that. Prayers are answered when believers abide in Christ.
John 15:7 If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
Abiding in Christ is keeping in fellowship with Him so His life can work in and through us to produce fruit. It involves the Word of God and confessing sin so that nothing hinders our communion with Him. When we abide in Christ we obey Him because we love Him. We have faith.
Faith calms our fears, cushions our falls, and confirms our future. Many believers never learn what God can do because they never believe.
