Ephesians 6:18-20 Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints; And for me, that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel, For which I am an ambassador in bonds: that therein I may speak boldly, as I ought to speak.
‘Praying always’ – praying must also be classed as part of the armour because it is an additional and very important part of the fight against spiritual powers of evil (Jas. 4:7; 1Pet. 5:8-9).
We have liberty in prayer [Greek: parrhesia] freedom of speech; liberty of access to God. Christians can have absolute confidence of access to God because all sins which separated us from Him are removed (Isa. 59:1-2). In the Old Testament days, men were not permitted to approach God. Even the mountain on which God gave the law was not to be touched by man or beast. Only the high priest was permitted in the holy of holies once a year, and even then, he could not approach God without proper atonement. Now we all have free and daily access to God by the blood of Jesus (Heb. 10:19-23; Eph. 2:18). We are invited to come boldly to the throne of grace to obtain help in time of need (Heb. 4:14-16). As long as we hold fast to his liberty of access to God, we are His house (Heb. 3:6). If sin is in life we do not and cannot have this liberty of access. God will not hear our prayers (1Jn. 3:20-23; 5:14-15).
‘Supplication’ [Greek: deesis] and entreating; continued strong and incessant pleadings until the prayer is answered (Lk. 18:1-8). Translated “request” (Php. 1:4); “supplication” (Acts 1:14; Eph. 6:18; Php. 4:6; 1Tim. 2:1; 5:5); and “prayer” 12 times.
‘Watching thereunto with all perseverance and supplication for all saints.’ Without this, prayer and Christian armour will be ineffectual (Mark 13:33; Lk. 21:36; Heb. 13:17).
‘Perseverance’ [Greek: proskarteresis] to adhere firmly to (Acts 2:42, 46; 6:4; 8:13; 10:7; Rom. 12:12; 13:6; Col. 4:2; Mark 3:9). Be close in pursuit of; always intent upon your object in prayer (Rom. 12:12).
‘Ambassador’ [Greek: presbeuo] an emperor’s legate. Such was held in respect in all civilized countries, but here the ambassador of the King of Heaven is in chains!
