It is impossible to get exhausted in work for God. We get exhausted because we try to do God's work in our own way.
Oswald ChambersA sentimentalist is one who delights to have high and devout emotions stirred whilst reading in an arm-chair, or in a prayer meeting, but he never translates his emotions into action. Consequently a sentimentalist is usually callous, self-centred and selfish, because the emotions he likes to have stirred do not cost him anything.
Oswald ChambersThe call of God is to preach the gospel--namely, the reality of redemption in our Lord Jesus Christ. The one passion of Paul's life was to proclaim the gospel of God. He welcomed heartbreak, disillusionment , and tribulation for only one reason--these things kept him unmovable in his devotion to the gospel of God.
Oswald ChambersThe expression of Christian character is not good doing, but God-likeness. If the Spirit of God has transformed you within, you will exhibit Divine characteristics in your life, not good human characteristics . God's life in us expresses itself as God's life, not as human life trying to be godly.
