Romans 3:25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;

Propitiation means acceptable substitute. You have to trust God is satisfied with you based on your faith in Christ’s death on the cross. Christ died nearly two thousand years ago. First century Christians witnessed His death and resurrection, we have to believe their witness and trust that God’s sense of justice is satisfied on our behalf.

Faith, trust and belief are mixed together for a reason.

Hebrews 4:2 For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.

These Jews believed God and trusted God but did not mix in the faith required to please God.

Hebrews 11:6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.

Belief and trust are dependent upon faith to accomplish that which is required to meet God’s plans. In many belief systems they define faith as belief, or trust while in fact they are three totally separate entities.

Belief is a rational study of a subject and decision based on self-satisfaction. Beliefs can and do changed based on better or newer information.

Trust is based on relevant understanding of terms and conditions. An understanding of those terms and conditions promotes a reliance upon the warrantor to stand behind a claim of performance. Failure of those terms and conditions, or the understanding of them breaks trust.

Faith from God, faith in God and faith thru God is the power to believe what you cannot see, trust what you cannot understand, and act out a life in relationship with the God of promise. The three must be mixed to produce the abundant life of John 10:10.
