John Trapp on Matthew 28:20

Verse 20. To observe all things] Our obedience must be entire; as for subject, the whole man, so for object, the whole law, That perfect law of liberty. The Gospel requireth, that in our judgements we approve, and in our practises prove, what that good and holy, and acceptable will of God is. Those be good Catholikes, saith Austin, qui & fidem integram [illegible: 1 word], & bonos mores. But let carnall gospellers either adde practise, or leave their profession: renounce the devil and all his works, or else renounce their baptisme. As Alexander the great bad one Alexander a coward in his army, change his name or be a [illegible: 1 word]. I am with you alway] viz. To preserve you from your enemies, prosper you in your enterprizes, and to do for you whatsoever heart can wish, or need require. When Christ saith I will be with you, you may adde what you will: to protect you, to direct you, to comfort you, to carry on the work of grace in you, and in the end to crown you with immortality and glory. All this and more, is included in this precious promise.
