“To this end I strenuously contend with all the energy Christ so powerfully works in me.”- ( Col 1:29)
” strenuously,” labor.., the word speaks of hard work, toiling, laboring to the point of exhaustion if necessary…
“Content,Striving,” – Thayer’s Definition “to enter a contest: contend in the gymnastic games to contend with adversaries, fight metaph. to contend, struggle, to endeavor with strenuous zeal, strive: to obtain something.”
The Amplified Bible puts it this way ...”For this I labor [unto weariness], striving with all the superhuman energy which He so mightily enkindles and works within me.”
As you can see it’s no walk in the park but requires effort , energy. But the good news it is Divine power enabling the believer to persevere … And v 28 shows in what ” We proclaim Him, admonishing every man and teaching every man with all wisdom, SO THAT we may present EVERY man complete in Christ.”
“SO THAT,” gives the reason, they proclaimed the Lord JESUS, admonishing,teaching every man…”so that” they could present every man mature in Christ. They labored for the benefit of others, pouring their lives into them for the exaltation of the LORD Jesus.
Perseverance in the faith is evidence of God’s power working within your soul !
