To accept Christ is to receive Him by faith as your Lord and Savior. But, strictly speaking, the great thing to see is that God has accepted Christ. He took our sins upon Himself, died to make propitiation (the sacrifice which removed the anger of God) for them. But God raised Him from the dead and has taken Him up to glory. God has accepted Christ in token of His perfect satisfaction in His work. Believing this, the soul enters into peace. I simply rest in Gods thoughts about His son.
