We may feel happy when someone is happy with a gift we gave to him and expresses thankfulness. But if he seems to feel uncomfortable about receiving it, we may also feel uncomfortable. We received the grace of God by which we sinners were freely justified, and it is the reason that we should lead a proper Christian life. If we fail to feel the love of God, however, we cannot believe Jesus was crucified for us and we find it difficult to live a Christian life. On the contrary, when we feel God's unconditional love for us, we will have no difficulty living by His Word.
